Sunan an-Nasa'i 1347

‘Amr ibn ‘Ali informed us; he said: Yahya narrated to us, from ‘Uthman al-Shahham, from Muslim ibn Abi Bakrah, who said: My father would say after the prayer: “O Allah, I seek refuge in You from disbelief, poverty, and the punishment of the grave.” I would say these words, and my father said, “My son, from whom did you learn this?” I said, “From you.” He said: “The Messenger of Allah (peace and blessings be upon him) would say them after the prayer.”
