Ali bin Husayn reported,

When they arrived in Medina from Yazid bin Muawiya after the killing of Husayn bin Ali, Miswar bin Makhrama met him and said to him, "Do you have any need that you would like me to attend to for you?"I said to him, "No."He said to him, "Will you give me the sword of the Messenger of Allah ﷺ? For I fear that the people will overpower you and take it. By Allah, if you give it to me, no one will ever reach it until my soul departs. Indeed, Ali bin Abu Talib proposed to marry the daughter of Abu Jahl while still married to Fatimah. I heard the Messenger of Allah ﷺ addressing the people about this from his pulpit, and I had reached puberty at that time. He said, 'Fatimah is from me, and I fear that she will be tested in her faith.' Then he mentioned a son-in-law of his from Banu Abd Shams and praised him regarding the marriage relationship between them, speaking well of him. He said, 'He spoke to me and was truthful with me, he made me a promise and fulfilled it. I do not forbid what is lawful nor permit what is forbidden, but by Allah, the daughter of the Messenger of Allah ﷺ and the daughter of the enemy of Allah will never be joined together in one place.'"

علي بن الحسين حدثه

أنهم حين قدموا المدينة من عند يزيد بن معاوية مقتل الحسين بن علي رضي الله عنهما لقيه المسور بن مخرمة فقال له هل لك إلي من حاجة تأمرني بها قال فقلت له لا قال له هل أنت معطي سيف رسول الله ﷺ فإني أخاف أن يغلبك القوم عليه وايم الله لئن أعطيتنيه لا يخلص إليه أبدا حتى تبلغ نفسي إن علي بن أبي طالب خطب بنت أبي جهل على فاطمة فسمعت رسول الله ﷺ وهو يخطب الناس في ذلك على منبره هذا وأنا يومئذ محتلم فقال إن فاطمة مني وإني أتخوف أن تفتن في دينها قال ثم ذكر صهرا له من بني عبد شمس فأثنى عليه في مصاهرته إياه فأحسن قال حدثني فصدقني ووعدني فأوفى لي وإني لست أحرم حلالا ولا أحل حراما ولكن والله لا تجتمع بنت رسول الله ﷺ وبنت عدو الله مكانا واحدا أبدا
