Ali bin Abu Talib reported,

I said, "Messenger of Allah, why do you choose carefully from among the women of Quraysh and overlook us?"He replied, "Do you have someone in mind?"I said, "Yes, the daughter of Hamza."The Messenger of Allah ﷺ said, "She is not lawful for me. She is the daughter of my brother through breastfeeding."
