Musnad Ahmad 26:135

Waki’ narrated to us, Sufyan narrated to us, from Abu Ishaq, from al-Aswad ibn Yazid, from Ibn Mas’ud: That the Prophet, peace and blessings of Allah be upon him, prostrated during [the recitation of] an-Najm, and the Muslims prostrated, except for a man from Quraysh who took a handful of soil, raised it to his forehead, and prostrated upon it. ‘Abdullah said: "And I saw him afterwards killed as a disbeliever."
