Sahih al-Bukhari, Volume 2, Book 19, Hadith 176 (USC-MSA) ⓘ
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."
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الأَسْوَدِ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم قَرَأَ سُورَةَ النَّجْمِ فَسَجَدَ بِهَا، فَمَا بَقِيَ أَحَدٌ مِنَ الْقَوْمِ إِلاَّ سَجَدَ، فَأَخَذَ رَجُلٌ مِنَ الْقَوْمِ كَفًّا مِنْ حَصًى أَوْ تُرَابٍ، فَرَفَعَهُ إِلَى وَجْهِهِ وَقَالَ يَكْفِينِي هَذَا، فَلَقَدْ رَأَيْتُهُ بَعْدُ قُتِلَ كَافِرًا.
