Is it lawful for a man to marry the mother of his stepmother?
Q 5:
Is it permissible for a man to marry the mother of his stepmother?
A:
It is permissible for a man to marry the mother of his stepmother because she is not one of those who are prohibited for him to marry due to lineage or marriage. The basic rule in everything is the permissibility as long as there is no proof that prohibits it. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
