He informed him that Ali bin Abu Talib proposed to marry the daughter of Abu Jahl while he was already married to Fatimah, daughter of the Prophet ﷺ. When Fatimah heard about this, she came to the Prophet ﷺ and said to him, "Your people are saying that you do not get angry for the sake of your daughters. Here is Ali about to marry the daughter of Abu Jahl."Miswar said, The Prophet ﷺ then stood up, and I heard him give the testimony of faith, after which he said, "To proceed. I gave my daughter in marriage to Abu al-As bin Rabi, and he spoke truthfully to me and kept his word. Fatimah bint Muhammad is a part of me, and I hate for anyone to put her through trial. By Allah, the daughter of the Messenger of Allah and the daughter of the enemy of Allah shall never be joined together with one man."So Ali withdrew his proposal.
