Prostrations during the recitation of the Qur'an

Narrated `Abdullah bin Mas`ud:

The Prophet (ﷺ) recited Suratan-Najm (103) at Mecca and prostrated while reciting it and those who were with him did the same except an old man who took a handful of small stones or earth and lifted it to his forehead and said, "This is sufficient for me." Later on, I saw him killed as a non-believer.
