Ubayd Allah narrated to us, Harami narrated to us, Shu'bah narrated to us, from Qatadah, from Anas ibn Malik, who said: My mother said, "O Prophet of Allah, your servant, so supplicate to Allah for him." He said, "O Allah, increase his wealth and his children, and bless him in what You have given him."
