Hadith 21.2
Prayer
He said that in the year of the Conquest* God's Messenger recited a verse at which a prostration should be made and all the people prostrated themselves. Some were mounted, some were prostrating themselves on the ground, and those who were mounted prostrated themselves on their hands. * i.e. the Conquest of Mecca in 8 A.H. Abu Dawud transmitted it.
وَعَن ابْنِ عُمَرَ أَنَّهُ قَالَ: إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَرَأَ عَامَ الْفَتْحِ سَجْدَةً فَسَجَدَ النَّاسُ كُلُّهُمْ مِنْهُمُ الرَّاكِبُ وَالسَّاجِدُ عَلَى الْأَرْضِ حَتَّى إِنَّ الرَّاكِبَ لَيَسْجُدُ عَلَى يَده. رَوَاهُ أَبُو دَاوُد
