The Messenger of Allah ﷺ mentioned Fatimah. She said, "I spoke up, and he said, 'Are you not pleased to be my wife in this world and the next?'I replied, 'Yes, by Allah.'He said, 'Then you are my wife in this world and the next.'"
أن رسول الله ﷺ ذكر فاطمة قالت: فتكلمت أنا فقال: أما ترضين أن تكوني زوجتي في الدنيا والآخرة؟ قلت: بلى والله، قال: فأنت زوجتي في الدنيا والآخرة.

Ibn Hibban (7095) and Hakim (4/10) both narrated it through the route of Yahya bin Saeed Umawi, who said, "My father told me, Abu Anbas Saeed bin Kathir told me, from his father (he is Kathir bin Ubayd Tamimi), who said, Ayesha narrated to us," and then he mentioned it.Kathir bin Ubayd Tamimi is the freed slave of Abu Bakr Siddiq, from Kufa. Ibn Hibban mentioned him among the trustworthy narrators, but I did not find anyone who confirmed his reliability. This is why Hafiz said of him in Taqrib, "acceptable," meaning when corroborated. I did not find a corroborating narration for him, but it is strengthened by the hadith of Ammar bin Yasir found in the sahih collections.
