Sahih al-Bukhari · Book 17: Prostration During Recital of Qur'an · Whoever recited the verses of prostration and did not prostrate
Narrated `Ata' bin Yasar:
حَدَّثَنَا سُلَيْمَانُ بْنُ دَاوُدَ أَبُو الرَّبِيعِ ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ ، قَالَ أَخْبَرَنَا يَزِيدُ بْنُ خُصَيْفَةَ ، عَنِ ابْنِ قُسَيْطٍ ، عَنْ عَطَاءِ بْنِ يَسَارٍ ، أَنَّهُ أَخْبَرَهُ، أَنَّهُ، سَأَلَ زَيْدَ بْنَ ثَابِتٍ ـ رضى الله عنه ـ فَزَعَمَ أَنَّهُ قَرَأَ عَلَى النَّبِيِّ صلى الله عليه وسلم {وَالنَّجْمِ} فَلَمْ يَسْجُدْ فِيهَا.
I asked Zaid bin Thabit about prostration on which he said that he had recited An-Najm before the Prophet, yet he (the Prophet) had not performed a prostration.
