Arabic (Original)
حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ أَخْبَرَنَا مُحَمَّدُ بْنُ مُطَرِّفٍ أَبُو غَسَّانَ اللَّيْثِيُّ عَنْ أَبِي الْحَصِينِ عَنْ أَبِي صَالِحٍ الْأَشْعَرِيِّ عَنْ أَبِي أُمَامَةَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الْحُمَّى كِيرٌ مِنْ جَهَنَّمَ فَمَا أَصَابَ الْمُؤْمِنَ مِنْهَا كَانَ حَظَّهُ مِنْ جَهَنَّمَ.
