It was narrated from ‘Amr bin Shu’aib, from his father, that his grandfather said:“I saw the Prophet (ﷺ) departing to his right and to his left when he finished the prayer.”
حَدَّثَنَا بِشْرُ بْنُ هِلاَلٍ الصَّوَّافُ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ حُسَيْنٍ الْمُعَلِّمِ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ رَأَيْتُ النَّبِيَّ ـ صلى الله عليه وسلم ـ يَنْفَتِلُ عَنْ يَمِينِهِ وَعَنْ يَسَارِهِ فِي الصَّلاَةِ .
