Hadith record

Hadith.5728 - Al-Hasan ibn Mahbub narrated from Ali ibn Ri'ab from Abu Basir who said: I asked Abu Jafar Imam Muhammad ibn Ali Al-Baqir (as) about a Muslim man who died and had a Christian mother, along with a Muslim wife and Muslim children. Imam (as) said: "If his mother accepts Islam before the inheritance is divided, she is given one-sixth." I asked: "What if he has no wife, no children, and no heir entitled to a share in the Book from among the Muslims, and his mother is Christian, and his relatives are Christians who would have a share in the Book if they were Muslim - who inherits his wealth?" Imam (as) said: "If his mother embraces Islam, then all of his inheritance belongs to her. But if his mother does not embrace Islam and some of his relatives who have a rightful share in the Book accept Islam, the inheritance goes to them. If none of his relatives become Muslim, then his inheritance belongs to the Imam."
