وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «اشْتَدَّ غَضَبُ اللَّهِ عَلَى قَوْمٍ فَعَلُوا بِنَبِيِّهِ» يُشِيرُ إِلَى رَبَاعِيَتِهِ «اشْتَدَّ غَضَبُ اللَّهِ عَلَى رَجُلٍ يَقْتُلُهُ رَسُولُ اللَّهِ فِي سَبِيلِ اللَّهِ» . مُتَّفَقٌ عَلَيْهِ وَهَذَا الْبَابُ خَالٍ عَنِ: الْفَصْلِ الثَّانِي
Abu Huraira reported God's messenger as saying, "God is very angry with people who have done this to their prophet (pointing to the tooth next his eyetooth). God is very angry with a man who is killed by God's messenger in God's path." (Bukhari and Muslim.)
