Prostrations during the recitation of the Qur‘an

Narrated 'Abdullah bin Masud :

The Prophet recited Surat an-Najm (53) at Mecca and prostrated while reciting it and those who were with him did the same except an old man who took a handful of small stones or earth and lifted it to his forehead and said, "This is sufficient for me." Later on, I saw him killed as a non-believer.

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا غُنْدَرٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، قَالَ سَمِعْتُ الأَسْوَدَ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ قَرَأَ النَّبِيُّ ﷺ النَّجْمَ بِمَكَّةَ فَسَجَدَ فِيهَا، وَسَجَدَ مَنْ مَعَهُ، غَيْرَ شَيْخٍ أَخَذَ كَفًّا مِنْ حَصًى أَوْ تُرَابٍ فَرَفَعَهُ إِلَى جَبْهَتِهِ وَقَالَ يَكْفِينِي هَذَا. فَرَأَيْتُهُ بَعْدَ ذَلِكَ قُتِلَ كَافِرًا.
