Repentance Made Manifest: From Highwayman to Ṣūfī in the Thought and Practice of al-Fuḍayl ibn ʿIyāḍ and Bishr al-Ḥāfī
by Jamal Ali Assadi, Mahmoud Naamneh and Khaled Sindawi

Abstract
This article offers a comparative study of two closely linked constellations of early Ṣūfī thought: the ascetic–mystical program of al-Fuḍayl ibn ʿIyāḍ (d. 187/803) and that of his renowned disciple Bishr al-Ḥāfī (d. 227/841).

This article offers a comparative study of two closely linked constellations of early Ṣūfī thought: the ascetic–mystical program of al-Fuḍayl ibn ʿIyāḍ (d. 187/803) and that of his renowned disciple Bishr al-Ḥāfī (d. 227/841). Moving beyond hagiographic anecdote, the study advances the thesis that the pair articulate two complementary modalities of tawba (repentance) that generate distinct ascetic habitus and pedagogical lineages: al-Fudayl’s “ethic of awe” (fear, juridical redress, and renunciation of patronage) and Bishr’s “aesthetics of reverence” (beauty-induced modesty, evident humility, and fame avoidance). Drawing on primary sources (Ḥilyat al-Awliyāʾ, al-Sulamī’s Ṭabaqāt al-Ṣūfiyya, al-Qushayrī’s Risāla, al-Sarrāj’s Lumaʿ), the article reconstructs each thinker’s core concepts, practices (e.g., returning wrongs, ḥafāʾ/barefoot humility), and teaching styles and maps how the teacher–disciple nexus transmits, adapts, and ritualizes these ethics into durable Ṣūfī dispositions. Methodologically, the article combines close textual analysis with practice theory to show how emotions—such as fear and modesty (ḥayāʾ)—are choreographed into public, socially legible acts, thus reframing repentance as embodied discipline rather than interior feeling alone. A prosopographic appendix traces transmission from al-Fudayl to Bishr to Sarī al-Saqaṭī and al-Junayd, clarifying how each modality survives in later Baghdad sobriety and Malāmatī self-effacement. The contribution is twofold: first, it supplies a granular typology of early Ṣūfī repentance that explains divergent stances toward money, publicity, and power; second, it models how to read early Ṣūfī biography as anthropology of practice, recovering the lived grammar by which “conversion stories” become social programs. In doing so, the article nuances standard narratives of early Ṣūfism, showing that Bishr is not merely al-Fuḍayl’s echo but a creative reframer whose “reverential” path complements—rather than imitates—the awe-driven ethic associated with al-Fuḍayl.

Improved maternal experiences and outcomes have been widely linked to the presence of birth companions. However, cultural norms, institutional constraints, and privacy concerns frequently restrict women’s choice of birth companions in many Middle Eastern countries, including Jordan. This study investigated Jordanian women’s beliefs and barriers about the presence of companions in the labour room. A qualitative descriptive study design was conducted using Braun and Clarke’s framework for thematic analysis. Thirteen women (ages 21 to 38 years) with prior pregnancy and childbirth experience were chosen from a free health awareness event in Irbid, Northern Jordan in July 2025, to participate in semi-structured interviews. The responses were recorded on audio tapes and subsequently stored in their original format. Data were coded, transcribed, and then thematically analyzed to identify beliefs and perceived barriers. The most significant beliefs were: (i) emotional and psychological support, wherein companionship was thought to alleviate fear and provide reassurance; (ii) strengthening family ties, as women saw shared childbirth experiences as improving family bonds; and (iii) cultural and religious interpretations, wherein female relatives were frequently seen as more acceptable than husbands. Women reported two barriers to allowing companions in the labour room: (i) privacy and modesty issues, where they feared embarrassment, exposure, and judgment, and (ii) institutional and policy restrictions, such as restrictive hospital regulations. Although Jordanian women recognized the emotional and interpersonal benefits of having company during childbirth, they encountered numerous substantial institutional, cultural, and privacy-related barriers. Improving women’s birth experiences and promoting respectful maternity care may be achieved by addressing these issues through culturally sensitive education, privacy-enhancing infrastructure, and regulatory reform.

In today’s digital world where presence is often equated with personal visibility, the choice of Emirati women to remain faceless on social media presents a powerful counter narrative—one that reveals the complexities of identity, modesty and belonging in a hyperconnected multicultural society. This study takes a closer look at how these women manage their online identities by intentionally choosing not to show their faces on Instagram. Using digital ethnography and thematic analysis, this article explores how they navigate the balance between global expectations of self-expression and the traditional values of modesty and honor. Over a three-month period, the study observes their activity on Instagram, analyzing shared images to see how facelessness becomes a form of agency. The findings highlight the tension between Western-centric paradigms of identity and selfhood, proposing digital veiling as a transferable framework for understanding how modesty, discretion and agency are negotiated across digital cultures. This article contributes to the broader conversation on digital identity, gendered representation and intercultural negotiation by foregrounding the silent yet strategic practices of women who remain unseen but not unheard.

This study examines Richard of Saint Victor’s conception of wisdom and love, understood as the ultimate ends of human life and deeply connected with the notion of care. For Richard, authentic care requires discerning the true object of concern: the human being as a rational creature created for happiness through knowledge and love of God. His anthropology highlights the dignity of man, composed of body, reason, and affection, and called to participate in divine happiness. Richard develops a spiritual pedagogy in which the ordering and moderation of affections—fear, sorrow, hope, love, joy, hatred, and modesty—are indispensable for the path toward contemplation. Through an allegorical reading of Jacob, his wives, and their children, Richard presents a symbolic itinerary where the progression of affectivity and reason leads ultimately to contemplation, embodied in Benjamin. This contemplative fulfillment transcends both fear and greed, liberating the human being from self-centeredness and opening him to love and divine wisdom. The work demonstrates Richard’s synthesis of Platonic, Augustinian, and Victorine traditions, proposing a transformative vision of the human person: happiness is inseparable from love, and wisdom is achieved not through rational argument but through the lived experience of love that surpasses reason.

Background: Modern rehabilitation approaches, encompassing physical, emotional, and social aspects, are gaining momentum in healthcare systems worldwide; however, their acceptance and effectiveness vary across different cultural contexts. Objective: This narrative review aims to produce a culturally informed overview of barriers and enablers, highlighting possible strategies to better align evidence-based rehabilitation with Saudi sociocultural realities. Methods: Drawing on literature from 2010 to 2024, this narrative review was conducted by searching the peer-reviewed literature from PubMed, Scopus, and the Saudi Digital Library using focused keywords. PICO framework was used to define inclusion and exclusion criteria. Relevant studies addressing cultural influences on rehabilitation adoption were included. Results: 1565 articles were initially identified from PubMed, Scopus, and the Saudi Digital Library. After careful screening, eight articles were included in the narrative review. We witnessed key factors relevant to the context of Saudi Arabia deriving health-seeking behaviors to be modesty, fatalism, family support, and religion. Factors possibly associated with the influence of physical therapy rehabilitation were gender, communication barriers, traditional healing practices, and culture and parental involvement. Conclusions: In Saudi Arabia, rehabilitation service utilization and practices may be prone to cultural factors. It is of utmost importance that healthcare providers step in and make sure that they sensitize themselves with cultural-specific awareness, knowledge, and competency to deliver optimal rehabilitation healthcare services that meet the standards and needs of the Saudi community.

This essay argues that female representations at Qusayr Amra reflect a deliberate adaptation of pre-Islamic artistic traditions, expressing evolving Umayyad ideas of beauty, gender, and hierarchy. By analyzing the interplay between visual imagery and written texts, including the Qur’an, it reevaluates the significance of female figures and the representational choices made in 8th-century Umayyad palaces in Bilad al-Sham. Drawing on scholars such as Garth Fowden and Nadia Ali, and informed by contemporary gender studies, this essay foregrounds how artistic choices regarding female imagery negotiate social ideals of belief, gender, and power. The analysis begins by examining the development of figurative imagery in early Islam and its cultural context. It then offers a close reading of a key fresco challenging assumptions about modesty and figural representation. Through comparative analysis with another Umayyad site, this study highlights the complexities and meanings of female depictions, revealing diverse interpretations across contexts. While Patron Walid II was not the sole author of these choices, his patronage was crucial in enabling a bold engagement with Islamic visual culture. In doing so, this essay offers new insights into the complexities of early Islamic visual culture and its negotiation of social values. Full article

Professional development (PD) for mathematics teachers often emphasizes transformative instructional change. However, a more modest, incremental approach may offer a higher likelihood of success in ways that complement transformational efforts. This Editorial discusses the potential advantages of incremental PD where teachers make small but meaningful improvements to their practice over time. We explore the differences between transformational PD and incremental PD as evidenced by the articles in this Special Issue. We also distinguish between varieties of incremental PD projects, from those that focus on a small piece of a larger instructional vision (piece-and-support incremental PD), those that set out to achieve a modest goal without appeal to a broader instructional transformation (modest-goal-with-support incremental PD), to a more radically modest approach that involves offering small, optional instructional suggestions without investments of time or training (nudge-based incremental PD). Ultimately, this Editorial, and this Special Issue as a whole, advocates for new conversations and investigations into how PD is structured and how the promoted instructional changes might spread among mathematics teachers.

The aim of this article is to present the main phases of transformation of the Franciscan church in Zagan. This church is one of the best-preserved mendicant order churches in Central Europe and Silesia. Until now, it has not been the subject of detailed research. Based on the findings, it was possible to identify the oldest church as a model example of the principles described in the Narbonne Constitutions. The late Gothic vaulting introduced during the reconstruction represents avant-garde solutions from the late 15th century. The evolution of the church interior’s forms in Zagan is presented against the backdrop of other churches in Central Europe and Poland. Special attention is given to the uniqueness of the church, which stands out among other conventual churches with its use of diamond and net vaults in the chancel and nave. Full article

The purpose of this review was to synthesize the available literature on breast cancer-screening barriers, facilitators, and interventions among U.S. African immigrants. Following the integrative review framework and PRISMA guidelines for reporting systemic reviews, five electronic databases were searched: PubMed, CINAHL, PsycINFO, Medline, and Google Scholar. Studies were included if they were published in English language journals after 1 January 2000 and reported data on breast cancer-screening barriers, facilitators, or interventions among U.S. African immigrants. Barriers and facilitators reported by studies were descriptively examined and synthesized by two authors and classified as aligning with one of the three levels of influences based on the social–ecological model (intrapersonal, interpersonal, and community). Interventions promoting breast cancer screening were narratively summarized. Search procedures retrieved 1011 articles, with 12 meeting the criteria for inclusion in the review (6 qualitative and 6 quantitative). Intrapersonal barriers included limited awareness, fear of pain, language barriers, health concerns, transportation issues, costs, and negative past experiences. Interpersonal barriers involved modesty, spiritual beliefs, and lack of support, while community-level barriers included provider and healthcare-system challenges. Regarding facilitators, past screening experiences and health insurance were the most commonly reported intrapersonal facilitators. The only interpersonal facilitator identified was observing other women experience a breast cancer diagnosis and undergo treatment. Community-level facilitators included appointment reminders, scheduling assistance, culturally congruent interpreters, transportation to screening facilities, and patient navigators. Three articles reported outcomes of breast cancer-screening interventions. All three were pilot studies and reported increased knowledge and attitudes regarding breast cancer screening following the respective interventions. One study examined the uptake of breast cancer screening following the intervention, with results indicating an increase in screening. Findings provide a comprehensive synthesis of factors influencing breast cancer screening among African immigrants and highlight the need for future research on the topic. This review was registered with Prospero (CRD42024502826) before the initiation of search procedures. Full article

In this article, we address a question that has been frequently asked: Why is the Iranian government unable to defeat the struggle by women against the compulsory hijab? What distinguishes women’s resistance from other forms of freedom and justice movements? We address these questions by highlighting women’s “resilient resistance” within the family domain as both flexible and sustainable. The article examines how the domestication of politics and the politicization of family have interconnected dynamics in Iran, as illustrated by the “Woman, Life, Freedom” movement. It shows how women have shifted the Iranian family from a collaborator of oppressive patriarchal power to a more egalitarian structure to accommodate their protests against the compulsory hijab. As the catalysts for this change, they succeeded in discrediting the Islamic Republic’s moral discourse based on the compulsory hijab as a manifestation of modesty for women. They also validated their own morality based on personal choice. Using ethnographic fieldwork, including participatory observation and in-depth interviews with movement participants, this paper shows how women’s invisible yet significant resistance within the family has transformed this institution and profoundly affected the broader political landscape of Iran. It examines a unique case where social transformation drives larger political change. Full article

Adolescence is a dynamic period of transition, and interaction with parents is important for successfully passing through it. This article presents results from a study of three transactional analysis theory personality constructs of adolescents and their parents—functional ego states, life positions, and stroke economy. The sample included 215 students from 12 to 16 years old and 215 parents from 30 to 55 years old. The results show significant differences between the ego states Adult, Adapted Child, Nurturing Parent and Normative Parent of the adolescents and their parents, which are more expressed in the parents. It was found that the life position, “I am OK—you are OK” is more strongly expressed in parents, while the life position, “I am not OK—you are not OK” is leading in adolescents. In their interactions with others, adolescents express modesty, self-doubt, and underestimation of their own success, while parents are more assertive, confident, and resilient in their behavior. The obtained results can be used in different programs to improve social interaction and increase the effectiveness of adolescent-parent relationships. Full article

A poor person–environment fit may bring various negative effects to older people’s independence and physical and psychological well-being. The presented study is especially valuable as it explores the challenges of living in cities in a country located in central and eastern Europe; namely, a less researched area when it comes to the quality of life of older people dwelling in an urban environment. The research questions that were explored are (1) what environmental pressures have people identified in the urban environment in Slovenia; and (2) what strategies have they used to deal with them? The study is based on 22 interviews with older people and three focus groups, that were then analysed using a thematic analysis approach. The study results identify a number of environmental pressures, which were divided into structural housing pressures, structural neighbourhood pressures, and formal and informal pressures. The analysis shows important behavioural responses, such as strategies of using formal and informal help, moving away from environmental pressures, mobility, actively involved in changing the environment, as well as attitudinal adaptation strategies, such as acceptance, resilience, using distraction, modesty and planning for the future. We further emphasize how these coping strategies are linked to individual and community capabilities, which function as a conversion factor. Full article

A proper diet increases the effectiveness of training and accelerates post-workout regeneration. One of the factors determining eating behaviour are personality traits, including those included in the Big Five model, i.e., neuroticism, extraversion, openness, agreeableness, and conscientiousness. The aim of this study was to analyse the personality determinants of peri-exercise nutritional behaviours among an elite group of Polish athletes practicing team sports. The study was conducted in a group of 213 athletes, using the author’s validated questionnaire of exercise-related nutrition behaviours and the NEO-PI-R (Neuroticism Extraversion Openness-Personality Inventory-Revised). A statistical analysis was performed using Pearson’s linear correlation and Spearman’s rank correlation coefficients as well as a multiple regression analysis, assuming a significance level of α = 0.05. It has been shown that the level of the overall index regarding normal peri-exercise eating behaviours decreased with increasing neuroticism (r = −0.18) and agreeableness (r = −0.18). An analysis of the relationship between the personality traits (sub-scales) of the Big Five model demonstrated that the overall index of proper peri-exercise nutrition decreased with the intensification of three neuroticism traits, i.e., hostility/anger (R = −0.20), impulsiveness/immoderation (R = −0.18), and vulnerability to stress/learned helplessness (R = −0.19), and four traits of agreeableness, i.e., straightforwardness/morality (R = −0.17), compliance/cooperation (R = −0.19), modesty (R = −0.14), and tendermindedness/sympathy (R = −0.15) (p < 0.05). A multiple regression analysis exhibited that the full model consisting of all the analysed personality traits explained 99% of the variance concerning the level of the proper peri-exercise nutrition index. In conclusion, the index of proper nutrition under conditions of physical effort decreases along with the intensification of neuroticism and agreeableness among Polish athletes professionally practicing team sports.

Adding recycled glass components to concrete mixes is a novel and sustainable option. Prior studies have recommended replacement ratios of 30% glass aggregates and 20% ground glass pozzolan as optimum substitutions in concrete mixes. The compressive strength of glass concrete has been shown to increase when glass components are used with these proportions. Less information is available on the flexural strength of such concrete, and no previous research has been conducted on the flexural capacity of glass concrete exposed to high temperatures. To bridge this knowledge gap, cured concrete cylinders and beam samples using various glass coarse aggregate and ground glass pozzolan replacement ratios were heat-treated in a furnace. The heat-affected samples were then tested for their compressive and flexural capacities. It was found that glass pozzolan increased the mix workability, while glass aggregates reduced it. The compressive strengths were modesty increased and the flexural capacities were drastically reduced (up to 93%) after heat exposure. Therefore, recycled sustainable glass concrete may be efficiently used in concrete compressive members and in properly designed flexural members. It can also be used efficiently in architectural non-load-bearing members for insulating and aesthetic effects. Full article

This article presents the results of a quantitative survey conducted on 4000 electric energy consumers in Spain, France, Italy, and Denmark. The results demonstrate differences in the effects of additional remuneration for using vehicle-to-grid (V2G) stations, depending on users’ reasons for saving electricity. Individuals with extrinsic financial motivations are sensitive to such incentives; the higher the remuneration is, the more willingness they demonstrate to use V2G. Although individuals with intrinsic (the desire to control spending) and ecological (caring for the environment) motivations are also interested in using V2G, no relationship can be observed between the sizes of the rewards and individuals’ desire to use the technology. Users are similarly encouraged by low (an extra 2.5% of energy for free) and high (an extra 20%) rewards. In contrast, individuals who display intrinsic general modesty (willingness to not waste things) motivations may even be discouraged: the higher the reward, the less interest they demonstrate in V2G. The article illustrates how different types of motivation can affect users’ interest in the innovative V2G concept, as well as underlining the importance of constructing intrinsic and altruistic motivations in the process of education.
