Arabic (Original)
حَدَّثَنَا وَكِيعٌ عَن سُفْيَانَ عَن أَبِي إِسْحَاقَ عَن عَبْدِ اللَّهِ بْنِ يَزِيدَ عَنِ الْبَرَاءِ قَالَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا رَفَعَ رَأْسَهُ مِنْ الرُّكُوعِ لَمْ يَحْنِ رَجُلٌ مِنَّا ظَهْرَهُ حَتَّى يَسْجُدَ ثُمَّ نَسْجُدَ.
English Translation
Waki' told us, from Sufyan, from Abu Ishaq, from 'Abdullah ibn Yazid, from al-Bara', who said: When the Messenger of Allah, peace and blessings be upon him, raised his head from bowing, none of us would bend his back until he prostrated, then we would prostrate.
