What did the Prophet Muhammad (peace be upon him) do when reciting Surat-an-Najm (53)?
 Narrated `Abdullah bin Mas`ud:                     The Prophet 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."
