Sahih Bukhari

Book 17: Prostration During Recital of Qur'an

Chapter 8

Whoever prostrated with the prostration of the reciter

باب مَنْ سَجَدَ لِسُجُودِ الْقَارِئِ

And Ibn Mas'ud asked Tamim bin Hadhlam, while he was a boy, to recite Surah and said to him, "Prostrate as you are our Imam." ​​
وَقَالَ ابْنُ مَسْعُودٍ لِتَمِيمِ بْنِ حَذْلَمٍ- وَهْوَ غُلاَمٌ- فَقَرَأَ عَلَيْهِ سَجْدَةً، فَقَالَ اسْجُدْ فَإِنَّكَ إِمَامُنَا فِيهَا.
Sahih al-Bukhari 1075
حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، قَالَ حَدَّثَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يَقْرَأُ عَلَيْنَا السُّورَةَ فِيهَا السَّجْدَةُ، فَيَسْجُدُ وَنَسْجُدُ، حَتَّى مَا يَجِدُ أَحَدُنَا مَوْضِعَ جَبْهَتِهِ‏.‏
Ibn `Umar:

When the Prophet (ﷺ) recited a Sura that contained the prostration he would prostrate and we would do the same and some of us (because of the heavy rush) could not find a place for prostration.
