"I heard 'Abdullah bin Yazid delivering a Khutbah. He said: 'Al-Bara, who was no liar,told us that when they prayed with the Messenger of Allah ﷺ would raise his head from bowing and they would remain standing until they saw him prostrate, then they would prostrate."' (Using translation from Nasāʾī 829)
حَدَّثَنَا الْبَرَاءُ وَكَانَ غَيْرَ كَذُوبٍ أَنَّهُمْ كَانُوا إِذَا صَلَّوْا مَعَ رَسُولِ اللهِ ﷺ فَرَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ قَامُوا قِيَامًا حَتَّى يَرَوْهُ قَدْ سَجَدَ فَيَسْجُدُوا
