Musannaf Ibn Abi Shayba 3:1860

Yazid ibn Harun narrated to us, from Shu'bah, from Abu Ishaq, from al-Aswad, from Abdullah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) prostrated during [the recitation of] Surah an-Najm, and there remained no one except that he prostrated with him, except for an old man who took a handful of soil and raised it to his forehead. He said: I indeed saw him killed as a disbeliever.
