We asked Khabbab: Did the Messenger of Allah ﷺ recit (the Quran) in the noon and afternoon prayers? He replied: Yes. We then asked: How did you know this? He said: By the shaking of his beard, may peace be upon him. (Using translation from Abū Dāʾūd 801)   

قُلْنَا لِخَبَّابٍ هَلْ كَانَ رَسُولُ اللهِ ﷺ يُقْرَأُ فِي الظُّهْرِ وَالْعَصْرِ؟ قَالَ «نَعَمْ» قُلْتُ بِأَيِّ شَيْءٍ كُنْتُمْ تَعْرِفُونَ؟ قَالَ «بِاضْطِرَابِ لِحْيَتِهِ»  

Al-Bara who is not a liar said; when they (the companions) raised their heads from bowing along with the Messenger of Allah ﷺ, they would stand up, and when they saw him that he went down in prostration, they would prostrate (following the prophet). (Using translation from Abū Dāʾūd 620)   

حَدَّثَنِي الْبَرَاءُ وَهُوَ غَيْرُ كَذُوبٍ أَنَّهُمْ «إِذَا صَلَّوْا مَعَ رَسُولِ اللهِ ﷺ وَرَفَعُوا رُءُوسَهُمْ مِنَ الرُّكُوعِ قَامُوا قِيَامًا حَتَّى يَرَوْهُ قَدْ سَجَدَ»
