مسلم:١٣٦٣bوَحَدَّثَنَا ابْنُ أَبِي عُمَرَ حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ حَدَّثَنَا عُثْمَانُ بْنُ حَكِيمٍ الأَنْصَارِيُّ أَخْبَرَنِي عَامِرُ بْنُ سَعْدِ بْنِ أَبِي وَقَّاصٍ عَنْ أَبِيهِ

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ ثُمَّ ذَكَرَ مِثْلَ حَدِيثِ ابْنِ نُمَيْرٍ وَزَادَ فِي الْحَدِيثِ وَلاَ يُرِيدُ أَحَدٌ أَهْلَ الْمَدِينَةِ بِسُوءٍ إِلاَّ أَذَابَهُ اللَّهُ فِي النَّارِ ذَوْبَ الرَّصَاصِ أَوْ ذَوْبَ الْمِلْحِ فِي الْمَاءِ
