Mishkat al-Masabih 29 Excellent Qualities and Description of the Prophet كتاب الفضائل والشمائل 38

وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَلَا تَعْجَبُونَ كَيْفَ يَصْرِفُ اللَّهُ عَنِّي شَتْمَ قُرَيْشٍ وَلَعْنَهُمْ؟ يَشْتُمُونَ مُذَمَّمًا وَيَلْعَنُونَ مُذَمَّمًا وَأَنَا مُحَمَّدٌ» . رَوَاهُ الْبُخَارِيُّ

Abu Huraira reported God’s messenger as saying, `Are you not astonished at the manner in which God turns away from me the reviling and cursing of Quraish? They revile one who is blameworthy ( mudhammam ) and curse one who is blameworthy, whereas I am Muhammad (praiseworthy).” Bukhari transmitted it.
