Imām Bukhārī narrates: 'Abdullāh ibn Maslamah narrated to us, from Imām Mālik, from Ishāq ibn 'Abdullāh ibn Abī Talhah, from Anas ibn Mālik, may Allāh be pleased with him, he narrated:
We used to pray the 'Asr prayer, then if a person went to the quarter of Banū 'Amr ibn 'Awf, he would find them praying the 'Asr prayer there.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كُنَّا نُصَلِّي الْعَصْرَ ثُمَّ يَخْرُجُ الإِنْسَانُ إِلَى بَنِي عَمْرِو بْنِ عَوْفٍ فَنَجِدُهُمْ يُصَلُّونَ الْعَصْرَ.
