Musnad Ahmad 32:1070

Bahz and Hajjaj narrated to us, they said: Sulayman ibn al-Mughirah narrated to us, from Thabit, from Anas: The Messenger of Allah (peace and blessings of Allah be upon him) entered upon us, and there was no one there but me, my mother, and my maternal aunt, Umm Haram. He said: "Stand up, so that I may lead you in prayer," at a time other than a prayer time. Hajjaj said: He said: So he led us in prayer. A man from the people said to Thabit: "Where did he place Anas?" He said: "He placed him on his right side." He said: Then he prayed for us, the people of the house, for every good of the good of this world and the Hereafter. My mother said: "O Messenger of Allah, your little servant, pray to Allah for him." He said: So he prayed for me for every good. Bahz said: "With good." And among the last of what he prayed for me with, he said: "O Allah, increase his wealth and his children, and bless him in them."
