Sahih al-Bukhari 1079

حَدَّثَنَا صَدَقَةُ، قَالَ أَخْبَرَنَا يَحْيَى، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يَقْرَأُ السُّورَةَ الَّتِي فِيهَا السَّجْدَةُ فَيَسْجُدُ وَنَسْجُدُ حَتَّى مَا يَجِدُ أَحَدُنَا مَكَانًا لِمَوْضِعِ جَبْهَتِهِ‏.‏

Narrated Ibn `Umar.:Whenever the Prophet (ﷺ) recited the Sura which contained the prostration of recitation he used to prostrate and then we too, would prostrate and some of us did not find a place for prostration
