Sahih al-Bukhari — Prostration During Recital of Qur'an — Hadith No: 1067
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.

Narrated `Abdullah bin Mas`ud:The Prophet (ﷺ) 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
