Abu Dawud Book 6, Hadith Number 2273.
Chapter : Not known.
Narated By Ali ibn AbuTalib : When we came out from Mecca, Hamzah’s daughter pursued us crying: My uncle. Ali lifted her and took her by the hand. (Addressing Fatimah he said:) Take your uncle’s daughter. She then lifted her. The narrator then transmitted the rest of the tradition. Ja’far said: She is my uncle’s daughter. Her maternal aunt is my wife. The Prophet (PBUH) decided in favour of her maternal aunt, and said: The maternal aunt is like mother.
