What category of men from among the family of a veiled woman are allowed to enter her home?
Some scholars deemed it permissible that a husband's full brother enters his wives homes.
The following are those for whom it is permissible for them to enter to women's houses and stay in seclusion with them: A husband and Mahram relatives such as a father, husband's father, son, brother's son, sister's son, paternal and maternal uncle. However, a husband's full, paternal half or maternal half brother is not a Maharm and thus may not stay in seclusion with her or see parts of her body that are unlawful to be seen.
