Sunan an-Nasa'i 1321

Qutaybah narrated to us; he said: ‘Abd al-‘Aziz—meaning al-Darawardi—narrated to us, from ‘Amr ibn Yahya, from Muhammad ibn Yahya ibn Habban, from his uncle Wasi‘ ibn Habban, who said: I said to Ibn ‘Umar, “Tell me about the prayer of the Messenger of Allah (peace and blessings be upon him). What was it like?” He mentioned the takbir, that is, he mentioned it, and said: “Peace be upon you, and the mercy of Allah,” to his right, and “Peace be upon you,” to his left.
