Musnad Ahmad 32:1709

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