مسلم:٢٦٠ – حَدَّثَنِي أَبُو بَكْرِ بْنُ إِسْحَاقَ أَخْبَرَنَا ابْنُ أَبِي مَرْيَمَ أَخْبَرَنَا مُحَمَّدُ بْنُ جَعْفَرٍ أَخْبَرَنِي الْعَلاَءُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ يَعْقُوبَ مَوْلَى الْحُرَقَةِ عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ جُزُّوا الشَّوَارِبَ وَأَرْخُوا اللِّحَى خَالِفُوا الْمَجُوسَ
