Sahih al-Bukhari · Book 10: Call to Prayers (Adhaan) · To recite (the Qur'an) quietly in the Zuhr and 'Asr prayers
Narrated Abu Ma`mar:
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ ، قَالَ حَدَّثَنَا جَرِيرٌ ، عَنِ الأَعْمَشِ ، عَنْ عُمَارَةَ بْنِ عُمَيْرٍ ، عَنْ أَبِي مَعْمَرٍ ، قُلْتُ لِخَبَّابٍ أَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَقْرَأُ فِي الظُّهْرِ وَالْعَصْرِ قَالَ نَعَمْ. قُلْنَا مِنْ أَيْنَ عَلِمْتَ قَالَ بِاضْطِرَابِ لِحْيَتِهِ.
We said to Khabbab "Did Allah's Messenger (ﷺ) used to recite in Zuhr and `Asr prayers?" He replied in the affirmative. We said, "How did you come to know about it?" He said, "By the movement of his beard."
