Narrated 'Abdullah:
حَدَّثَنَا عَبْدَانُ بْنُ عُثْمَانَ ، قَالَ أَخْبَرَنِي أَبِي ، عَنْ شُعْبَةَ ، عَنْ أَبِي إِسْحَاقَ ، عَنِ الأَسْوَدِ ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَرَأَ {وَالنَّجْمِ} فَسَجَدَ بِهَا، وَسَجَدَ مَنْ مَعَهُ، غَيْرَ أَنَّ شَيْخًا أَخَذَ كَفًّا مِنْ تُرَابٍ فَرَفَعَهُ إِلَى جَبْهَتِهِ فَقَالَ يَكْفِينِي هَذَا. قَالَ عَبْدُ اللَّهِ فَلَقَدْ رَأَيْتُهُ بَعْدُ قُتِلَ كَافِرًا.
The Prophet (ﷺ) recited Surat-an-Najm and then prostrated himself, and all who were with him prostrated too. But an old man took a handful of dust and touched his forehead with it saying, "This is sufficient for me." Later on I saw him killed as an infidel.
