Arabic hadith text
حَدَّثَنَا هَنَّادُ بْنُ السَّرِيِّ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ سَعِيدِ بْنِ مَسْرُوقٍ، عَنْ عَبَايَةَ،
بْنِ رِفَاعَةَ عَنْ جَدِّهِ، رَافِعِ بْنِ خَدِيجٍ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ
" إِنَّالْحُمَّى فَوْرٌ مِنْ جَهَنَّمَ فَابْرُدُوهَا بِالْمَاءِ "
Translation
