Musnad Abu Ya'la al-Mawsili 116:24

Ahmad narrated to us, Hajjaj narrated to us, Shu'bah narrated to us, I heard Qatadah, from Anas bin Malik, from Umm Sulaym, that she said: "O Messenger of Allah, Anas is your servant, so supplicate to Allah for him." He said: "O Allah, increase his wealth and his children, and bless for him in what You have given him." Anas said: "Some of my children informed me that I have buried of my children and my children's children more than one hundred."
