Arabic (Original)
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا بَكْرُ بْنُ مُضَرَ عَنْ عُبَيْدِ اللَّهِ بْنِ زَحْرٍ عَنْ عَلِيِّ بْنِ يَزِيدَ عَنِ الْقَاسِمِ عَنْ أَبِي أُمَامَةَ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ لَتُسَوُّنَّ الصُّفُوفَ أَوْ لَتُطْمَسَنَّ وُجُوهُكُمْ وَلَتُغْمِضُنَّ أَبْصَارَكُمْ أَوْ لَتُخْطَفَنَّ أَبْصَارُكُمْ.
