Book 4: Prayer

Ibn Mas'ud said that the Prophet (ﷺ) recited "By the star”(Al-Qur’an; 53) prostrating himself when doing so, as did those who were with him with the exception of an old man of Quraish who took a handful of pebbles or dust and raised it to his forehead saying. "This is enough for me.” ‘Abdallah (i.e. Ibn Mas’ud) said that he later saw him killed as an infidel. (Bukhari and Muslim.) Bukhari added in a version that he was Umayya b. Khalaf.

Ibn ‘Abbas said that the Prophet (ﷺ) prostrated himself when reciting Sad (Al-Qur’an; 38) and said, "David made this prostration in repentance, but we do it out of gratitude.” Nasa’i transmitted it.
