حَدَّثَنَا يَحْيَى عَنْ عُبَيْدِ اللَّهِ أَخْبَرَنِي نَافِعٌ عَنِ ابْنِ عُمَرَ قَالَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقْرَأُ عَلَيْنَا السُّورَةَ فَيَقْرَأُ السَّجْدَةَ فَيَسْجُدُ وَنَسْجُدُ مَعَهُ حَتَّى مَا يَجِدُ أَحَدُنَا مَكَانًا لِمَوْضِعِ جَبْهَتِهِ
مسند امام احمد بن حنبل · Hadith 4669
It was narrated that Ibn 'Umar said: The messenger of Allah (PBUH) used to recite a soorah to us, and when he recited a soorah in which a prostration was required, he would prostrate and we would prostrate with him, until some of us could not find any spot for his forehead.
