Sahih Muslim 576
Abdullah (b. 'Umar) reported:
The Apostle of Allah (ﷺ) recited (Surat) al Najm and performed prostration during its recital and all those who were along with him also prostrated themselves except one old man who took a handful of pebbles or dust in his palm and lifted it to his forehead and said: This is sufficient for me. 'Abdullah said: I saw that he was later killed in a state of unbelief.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَمُحَمَّدُ بْنُ بَشَّارٍ، قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، قَالَ سَمِعْتُ الأَسْوَدَ، يُحَدِّثُ عَنْ عَبْدِ اللَّهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَرَأَ ‏{‏ وَالنَّجْمِ‏}‏ فَسَجَدَ فِيهَا وَسَجَدَ مَنْ كَانَ مَعَهُ غَيْرَ أَنَّ شَيْخًا أَخَذَ كَفًّا مِنْ حَصًى أَوْ تُرَابٍ فَرَفَعَهُ إِلَى جَبْهَتِهِ وَقَالَ يَكْفِينِي هَذَا ‏.‏ قَالَ عَبْدُ اللَّهِ لَقَدْ رَأَيْتُهُ بَعْدُ قُتِلَ كَافِرًا ‏.‏
