Narrated 'Abdullah bin Masud:
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.
