I never saw the Messenger of Allah ﷺ hold a wedding feast for any of his wives like the one he held for her. He held the feast with a sheep.
حدثنا مسدد وقتيبة بن سعيد قالا حدثنا حماد عن ثابت قال ذكر تزويج زينب بنت جحش عند
ما رأيت رسول الله ﷺ أولم على أحد من نسائه ما أولم عليها أولم بشاة
Bukhari narrated it in the Book of Marriage, Chapter: On one who held a wedding feast for some of his wives more lavishly than others, hadith 5171, from Musaddad. Muslim also narrated it in the Book of Marriage, Chapter: The marriage of Zaynab bint Jahsh, the revelation of the hijab, and the establishment of the wedding feast, hadith 1428, from Qutayba, with the same chain.Hammad here is Ibn Zayd.
