The most beloved of women to the Messenger of Allah ﷺ was Fatimah, and from among the men, Ali. Ibrahim bin Saeed said, meaning from among his household.
حدثنا إبراهيم بن سعيد الجوهري حدثنا الأسود بن عامر عن جعفر الأحمر عن عبد الله بن عطاء
كان أحب النساء إلى رسول الله ﷺ فاطمة ومن الرجال علي قال إبراهيم بن سعيد يعني من أهل بيته
Grading, its isnad is daif. Tabarani also reported it in al-Awsat, no. 7258, from the hadith of Ibrahim bin Saeed Jawhari with the same wording, and Hakim graded it sahih, 3/155, and Dhahabi agreed with him, but its chain is daif, since Abdullah bin Ata was a mudallis and narrated with ambiguous transmission ("an"). See the hadith that follows, no. 3874.
