It is narrated from Sayyiduna Ali (may Allah be pleased with him) that he said: When we left Makkah, the daughter of Sayyiduna Hamzah (may Allah be pleased with him) followed us, calling out: O uncle! O uncle! I took her by the hand and handed her over to Sayyidah Fatimah (may Allah be pleased with her), saying: Take care of your cousin. When we reached Madinah, Sayyiduna Zayd, Sayyiduna Ja'far and I (may Allah be pleased with them) disagreed about her upbringing. I said: I took her with me, and she is my cousin. Sayyiduna Zayd said: She is the daughter of my (religious) brother. And Sayyiduna Ja'far said: She is my cousin, and her maternal aunt (Asma' bint Umays) is married to me. The Messenger of Allah (peace and blessings be upon him) said to Ja'far: "You resemble me in appearance and in character." He said to Zayd: "You are our brother and our freed slave (mawla)." And he said to me: "You are from me and I am from you." Then he (peace and blessings be upon him) decided: "Hand the girl over to her maternal aunt, for the maternal aunt holds the rank of a mother." I said: O Messenger of Allah! Will you not marry her? He (peace and blessings be upon him) said: "She is the daughter of my foster brother." This hadith has an authentic chain (sahih al-isnad), but the two Shaykhs did not record it with these words; however, they agreed upon the abridged narration of Abu Ishaq from al-Bara' bin Azib.
