Sunan an-Nasa'i 1142

Ishaq ibn Ibrahim reported to us; he said: Al-Fadl ibn Dukayn and Yahya ibn Adam informed us; they both said: Zuhayr narrated to us, from Abu Ishaq, from ‘Abd al-Rahman ibn al-Aswad, from his father, and from ‘Alqamah, from ‘Abdullah, who said: I saw the Messenger of Allah (ﷺ) proclaim the takbir with every lowering and rising, while standing and sitting. He gave the salutation to his right and his left, saying, “Peace be upon you and the mercy of Allah,” until the whiteness of his cheeks could be seen. He also said: I saw Abu Bakr and ‘Umar (may Allah be pleased with them both) do the same.
