Arabic (Original)
حَدَّثَنَا يَزِيدُ هُوَ ابْنُ هَارُونَ أَخْبَرَنَا مُحَمَّدُ بْنُ مُطَرِّفٍ عَنْ أَبِي الْحَصِينِ عَنْ أَبِي صَالِحٍ الْأَشْعَرِيِّ عَنْ أَبِي أُمَامَةَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الْحُمَّى مِنْ كِيرِ جَهَنَّمَ فَمَا أَصَابَ الْمُؤْمِنَ مِنْهَا كَانَ حَظَّهُ مِنْ النَّارِ.
English Translation
Yazid, who is ibn Harun, told us: Muhammad ibn Mutarrif informed us, from Abu al-Husayn, from Abu Salih al-Ash'ari, from Abu Umamah, from the Prophet, peace and blessings be upon him, who said: The fever is from the blast of Hell, so whatever of it afflicts the believer is his share of the Fire.
