Sahih Muslim 576

Muhammad ibn al-Muthanna and Muhammad ibn Bashshar narrated to us; they said: Muhammad ibn Ja‘far narrated to us; Shu‘bah narrated to us, from Abu Ishaq, who said: I heard al-Aswad narrating from Abdullah, from the Prophet (peace and blessings be upon him), that he recited “By the star when it sets” (Qur’an 53:1) and prostrated during it, and those with him prostrated as well. But an old man took a handful of pebbles or dust, raised it to his forehead, and said, “This is enough for me.” Abdullah said: I later saw him killed as an unbeliever.
