Musnad Abu Ya'la al-Mawsili 147:55

Abu al-Rabi' al-Zahrani narrated to us, Hammad bin Zayd narrated to us, from Sinan bin Rabi'ah, from Anas bin Malik, who said: My mother took me to the Messenger of Allah, may Allah bless him and grant him peace, and said: "O Messenger of Allah, your little servant, so supplicate to Allah for him." He said: "O Allah, increase his wealth and his children, lengthen his life, and forgive him." He said: So my wealth increased until I would harvest twice in a year, and my children increased until I have buried more than one hundred from my own loins, and my life has lengthened until I have become shy before my family and I have longed to meet my Lord. As for the fourth, meaning the forgiveness.
