Prostration During Recital of Qur'an
Chapter: The prostration in An-Najm (No. 53)
Narrated `Abdullah bin Mas`ud:
The Prophet (ﷺ) recited Surat-an-Najm (53) and prostrated while reciting it and all the people prostrated and a man amongst the people took a handful of stones or earth and raised it to his face and said, "This is sufficient for me. Later on I saw him killed as a non-believer."
