Maliks Muwatta Book 027, Hadith Number 012.

Section : Inheritance from People of Other Religions.

Yahya related to me from Malik from Yahya ibn Said from Sulayman ibn Yasar that Muhammad ibn al-Ashath told him that he had a christian or jewish paternal aunt who died. Muhammad ibn al-Ashath mentioned that to Umar ibn al-Khattab and said to him, "Who inherits from her?" Umar ibn al-Khattab said to him, "The people of her deen inherit from her." Then he went to Uthman ibn Affan, and asked him about that. Uthman said to him, "Do you think that I have forgotten what Umar ibn al-Khattab said to you? The people of her deen inherit from her."
