Musnad Abu Ya'la al-Mawsili 117:249

Zuhayr narrated to us, Affan narrated to us, Hammad narrated to us, from Thabit, from Anas, who said: When the Messenger of Allah (peace and blessings of Allah be upon him) would go to his bed, he would say: "Praise be to Allah who fed us, gave us drink, sufficed us, and sheltered us; for how many are there who have no one to suffice them and no one to shelter them."
