Sahih al-Bukhari · Book 17: Prostration During Recital of Qur'an · Prostrations during the recitation of the Qur'an
Narrated `Abdullah bin Mas`ud:
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 صلى الله عليه وسلم 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.
The Prophet (ﷺ) recited Suratan-Najm (103) 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.
