الترمذي:١٩٤١ – حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ الْعُكْلِيُّ حَدَّثَنِي أَبُو سَلَمَةَ الْكِنْدِيُّ حَدَّثَنَا فَرْقَدٌ السَّبَخِيُّ عَنْ مُرَّةَ بْنِ شَرَاحِيلَ الْهَمْدَانِيِّ وَهُوَ الطَّيِّبُ عَنْ أَبِي بَكْرٍ الصِّدِّيقِ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ مَلْعُونٌ مَنْ ضَارَّ مُؤْمِنًا أَوْ مَكَرَ بِهِ  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ غَرِيبٌ
