Hadith
حَدَّثَنَا مُحَمَّدُ بْنُ عُثْمَانَ الدِّمَشْقِيُّ أَبُو الْجُمَاهِرِ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي ابْنَ مُحَمَّدٍ - عَنْ مُصْعَبِ بْنِ ثَابِتِ بْنِ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَرَأَ عَامَ الْفَتْحِ سَجْدَةً فَسَجَدَ النَّاسُ كُلُّهُمْ مِنْهُمُ الرَّاكِبُ وَالسَّاجِدُ فِي الأَرْضِ حَتَّى إِنَّ الرَّاكِبَ لَيَسْجُدُ عَلَى يَدِهِ .
Narrated Abdullah ibn Umar: In the year of Conquest the Messenger of Allah (ﷺ) recited a verse at which a prostration should be made and all the people prostrated themselves. Some were mounted, and some were prostrating themselves on the ground, and those who were mounted prostrated themselves on their hands
