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.
كَانَ النَّبِيُّ ﷺ يَقْرَأُ السُّورَةَ الَّتِي فِيهَا السَّجْدَةُ فَيَسْجُدُ وَنَسْجُدُ حَتَّى مَا يَجِدُ أَحَدُنَا مَكَانًا لِمَوْضِعِ جَبْهَتِهِ
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.
كَانَ النَّبِيُّ ﷺ يَقْرَأُ عَلَيْنَا السُّورَةَ فِيهَا السَّجْدَةُ فَيَسْجُدُ وَنَسْجُدُ حَتَّى مَا يَجِدُ أَحَدُنَا مَوْضِعَ جَبْهَتِهِ
When the Prophet ﷺ recited Surat As-Sajda and we were with him, he would prostrate and we also would prostrate with him and some of us (because of the heavy rush) would not find a place (for our foreheads) to prostrate on.
كَانَ النَّبِيُّ ﷺ يَقْرَأُ السَّجْدَةَ وَنَحْنُ عِنْدَهُ فَيَسْجُدُ وَنَسْجُدُ مَعَهُ فَنَزْدَحِمُ حَتَّى مَا يَجِدُ أَحَدُنَا لِجَبْهَتِهِ مَوْضِعًا يَسْجُدُ عَلَيْهِ
The Messenger of Allah ﷺ while reciting the Qur'an recited its surah containing sajda, and he performed prostration and we also prostrated along with him (but we were so overcrowded) that some of us could not find a place for our forehead (when prostrating ourselves).
أَنَّ النَّبِيَّ ﷺ كَانَ يَقْرَأُ الْقُرْآنَ فَيَقْرَأُ سُورَةً فِيهَا سَجْدَةٌ فَيَسْجُدُ وَنَسْجُدُ مَعَهُ حَتَّى مَا يَجِدُ بَعْضُنَا مَوْضِعًا لِمَكَانِ جَبْهَتِهِ
The Messenger of Allah ﷺ would recite to us a surah (according to the version of Ibn Numair) outside the prayer (the agreed version goes), then he would prostrate along with him, and none of us could find a place for his forehead.
كَانَ رَسُولُ اللَّهِ ﷺ يَقْرَأُ عَلَيْنَا السُّورَةَ قَالَ ابْنُ نُمَيْرٍ فِي غَيْرِ الصَّلاَةِ ثُمَّ اتَّفَقَا فَيَسْجُدُ وَنَسْجُدُ مَعَهُ حَتَّى لاَ يَجِدُ أَحَدُنَا مَكَانًا لِمَوْضِعِ جَبْهَتِهِ
[Machine] "That the Messenger of Allah ﷺ used to offer prayer, meaning reciting the prostration verse (sajdah), outside of prayer, so he would prostrate and we would prostrate with him, until perhaps none of us could find a place to prostrate."
أَنَّ رَسُولَ اللهِ ﷺ كَانَ يُصَلِّي يَعْنِي يَقْرَأُ السَّجْدَةَ فِي غَيْرِ صَلَاةٍ فَيَسْجُدُ وَنَسْجُدُ مَعَهُ حَتَّى رُبَّمَا لَمْ يَجِدْأَحَدُنَا مَكَانًا يَسْجُدُ فِيهِ
The Messenger of Allah ﷺ would recite to us a surah (according to the version of Ibn Numair) outside the prayer (the agreed version goes), then he would prostrate along with him, and none of us could find a place for his forehead. (Using translation from Abū Dāʾūd 1412)
كَانَ رَسُولُ اللهِ ﷺ يَقْرَأُ عَلَيْنَا السُّورَةَ فَيَقْرَأُ السَّجْدَةَ فَيَسْجُدُ وَنَسْجُدُ مَعَهُ حَتَّى مَا يَجِدُ أَحَدُنَا مَكَانًا لِمَوْضِعِ جَبْهَتِهِ
