salam aleikum. i have one question which me and one other sister have been discussing. is it ok to marry ones husbands brother? i have hear that its ok if ones husband dies but my friend say thats its ok even if the husband dont die, that its enough to only be divorced by the husband and after its halal to marry the brother.

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.

The wife of one’s brother is not unmarriageable to him forever; rather, as soon as the marriage between her and her husband ends through divorce or death and her ‘Iddah (waiting period) lapses, it becomes permissible for the brother of her ex-husband to marry her.
