Sahih al-Bukhari 4073Book 64, Hadith 118
حَدَّثَنَا إِسْحَاقُ بْنُ نَصْرٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، عَنْ مَعْمَرٍ، عَنْ هَمَّامٍ، سَمِعَ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " اشْتَدَّ غَضَبُ اللَّهِ عَلَى قَوْمٍ فَعَلُوا بِنَبِيِّهِ ـ يُشِيرُ إِلَى رَبَاعِيَتِهِ ـ اشْتَدَّ غَضَبُ اللَّهِ عَلَى رَجُلٍ يَقْتُلُهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي سَبِيلِ اللَّهِ ".
Allah's Messenger (ﷺ) (pointing to his broken canine tooth) said, "Allah's Wrath has become severe on the people who harmed His Prophet. Allah's Wrath has become severe on the man who is killed by the Apostle of Allah in Allah's Cause."
