Musnad Abu Ya'la al-Mawsili 3:145

Abu Kurayb Muhammad ibn al-Ala al-Hamdani narrated to us, Ibn Abi Za’idah narrated to us, from his father, from Abu Ishaq, from Hani ibn Abi Hani, from Ali, that the Messenger of Allah (peace and blessings of Allah be upon him) decreed the daughter of Hamzah to her maternal aunt, and he said: "The maternal aunt is in the position of the mother." Ali, Ja’far, and Zayd had disputed over her.
