The daughter of Hamza was mentioned to the Prophet ﷺ, and he said, "She is the daughter of my brother through breastfeeding."
حدثنا يحيى عن شعبة حدثنا قتادة قال سمعت جابر بن زيد
ذكر للنبي ﷺ ابنة حمزة فقال إنها ابنة أخي من الرضاعة
Its isnad is sahih. Jabir bin Zayd is Abu Shatha. Bukhari and Muslim narrated the hadith with a similar meaning. See Muntaqa 3858. See also what came before in the Musnad of Ali, 1357. And see 931, 2040, and 2490.
