Allah named the male maḥārim of a woman: father, son, brother, nephew (brother's son), nephew (sister's son), women, and those she rightfully holds. The list defines the inner circle.

Sūrah al-Aḥzăb verse 55 completes the bilateral maḥārim framework. Day 198's verse (al-Nisāʾ 4:23) named the women forbidden in marriage from a man's perspective; today's verse names the male maḥārim from a woman's perspective. The two together define the inner-family circle in which cross-gender relationships are structurally protected and freely engaged. Read the verse carefully. 'lă junăḥa ʿalayhinna fī ăbăʾihinna wa-lă abnăʾihinna wa-lă ikhwănihinna wa-lă abnăʾi ikhwănihinna wa-lă abnăʾi akhawătihinna wa-lă nisăʾihinna wa-lă mă malakat aymănuhunn'. There is no blame on them in (showing themselves to) their fathers, their sons, their brothers, their brothers' sons, their sisters' sons, their women, or those whom their right hands possess. The list provides the woman's male maḥārim (those with whom marriage is permanently forbidden and with whom the veiling requirement is relaxed). Read each category. Father (ab): the biological father; by extension grandfather, great-grandfather. Son (ibn): the biological son; by extension grandson, great-grandson. Brother (akh): full or half brother. Brother's son (ibn al-akh): nephew through brother. Sister's son (ibn al-ukht): nephew through sister. The verse also names 'their women' (their fellow believing women, with whom modesty has its own internal rules) and 'those whom their right hands possess' (in the historical slavery context). The classical fiqh extends the list to include, by other verses and ahadith, the maternal uncle (khăl), the paternal uncle (ʿamm), the father-in-law (ḥamū), the son-in-law, the step-son under guardianship (where consummation has occurred with the mother), and the milk-relatives in these categories. The complete maḥārim list for a woman, derived from the Qurʾan and Sunnah: blood-fathers (and ancestors); blood-sons (and descendants); blood-brothers (full or half); paternal uncles; maternal uncles; nephews from siblings of either gender; milk-relatives in all these categories; in-law relatives in specific categories (her husband's father after his death or in her marriage; her husband's sons from another marriage; her own father's wives after the father's death; etc., per the detailed fiqh of muṣăharah). Within this circle, the woman does not need to wear the full ḥijăb in front of these male relatives at home (the exact extent of permitted relaxation varies by fiqh, but the basic principle is that maḥārim are not non-mahram strangers); the relationships are structurally protected from sexual ambiguity; the kinship is pure. The verse closes with: 'wa-ittaqīna Allăha inna Allăha kăna ʿală kulli shayʾin shahīd'. And fear Allah; indeed Allah is, over all things, Witness. Read what this closing adds. Even within the maḥārim circle, where veiling is not required and interaction is free, the structural awareness of Allah is preserved. The relaxation of the veiling-requirement does not mean the relaxation of all other modesty-disciplines. The believing woman is reminded: Allah witnesses your conduct even within the family circle; do not allow the relaxation to drift into immodesty even with maḥārim. The verse's closing is a structural safeguard. Now consider modern application. Many modern Muslim women, in mixed family-gatherings, are unclear about which male relatives are maḥārim and which are not. The categories are sometimes confused, especially in extended family contexts where cousins, in-laws of various degrees, and family-friends create ambiguity. The fiqh provides clarity. Cousins (children of paternal or maternal uncles/aunts) are not maḥārim; veiling-requirements apply. The brother-in-law (husband's brother) is not maḥārim; the Prophet ﷺ's famous warning about al-ḥamū being 'death' addresses this exactly (Day 33 khalwah). The father-in-law is maḥārim. The son-in-law is maḥārim. The husband's sons from another marriage are maḥārim (after the woman's consummation with the husband). The husband's father after his death is maḥārim. The categories are precise; the believer should learn them rather than guessing. The cure has three motions. First, learn your maḥārim list precisely. Whether you are male (applying 4:23 plus extensions) or female (applying 33:55 plus extensions), know who is in the circle and who is not. Second, structure family-gatherings with the categories in mind. Where non-maḥārim cross-gender interactions are present (cousins, brothers-in-law of the woman, sisters-in-law of the man, etc.), maintain the broader Islamic etiquette. Third, within the maḥārim circle, enjoy the structural openness Allah designed; the family relationships with maḥārim are pure kinship; they are the protected core of the family-life. Pray today: Allāhumma 'ajʿalnī mim man yuḥăfiẓu ʿală ḥudūdika fī al-ʿalăqăti, muḥsinīan fī kulli dăʾirah. O Allah, make me of those who preserve Your limits in relationships, doing excellence in every circle.
