Narrated `Abdullah:The Prophet (ﷺ) recited Surat An-Najam and prostrated, and there was nobody who did not prostrate then except a man whom I saw taking a handful of pebbles, lifting it, and prostrating on it. He then said, "This is sufficient for me." No doubt I saw him killed as a disbeliever afterwards.
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، عَنِ الأَسْوَدِ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه قَالَ قَرَأَ النَّبِيُّ صلى الله عليه وسلم النَّجْمَ، فَسَجَدَ فَمَا بَقِيَ أَحَدٌ إِلاَّ سَجَدَ، إِلاَّ رَجُلٌ رَأَيْتُهُ أَخَذَ كَفًّا مِنْ حَصًا فَرَفَعَهُ فَسَجَدَ عَلَيْهِ وَقَالَ هَذَا يَكْفِينِي. فَلَقَدْ رَأَيْتُهُ بَعْدُ قُتِلَ كَافِرًا بِاللَّهِ.
