Musnad Ahmad 32:113

Ibn Abi ‘Adi narrated to us, from Humayd, from Anas, who said: The Messenger of Allah (peace and blessings of Allah be upon him) entered upon Umm Sulaym, and she brought him dates and ghee, and he was fasting. He said: "Return your dates to their container and your ghee to its skin." Then he stood in a corner of the house and prayed two rak'ahs, and we prayed with him. Then he supplicated for Umm Sulaym and her family for good. Umm Sulaym said: "O Messenger of Allah, I have a small private request." He said: "What is it?" She said: "Your servant, Anas." He said: So he did not leave any good of the Hereafter or this world except that he supplicated for me with it. He said: "O Allah, provide him with wealth and children, and bless him in them." He said: There is no person among the Ansar who has more wealth than I. And he mentioned that he did not possess gold or silver, other than his ring. He said: And he mentioned that his eldest daughter, Aminah, informed him that he had buried from his loins [i.e., his offspring] up to the arrival of Al-Hajjaj, more than one hundred and twenty.
