ʿAbdullah bin ʿUmar said, "The Prophet ﷺ said, 'Fever is from the heat of Hell, so put it out (cool it) with water.' " Nafiʿ added: ʿAbdullah used to say, "O Allah! Relieve us from the punishment," (when he suffered from fever).

عَنِ النَّبِيِّ ﷺ قَالَ الْحُمَّى مِنْ فَيْحِ جَهَنَّمَ فَأَطْفِئُوهَا بِالْمَاءِ قَالَ نَافِعٌ وَكَانَ عَبْدُ اللَّهِ يَقُولُ اكْشِفْ عَنَّا الرِّجْزَ

Fever is from the vehement raging of the fire of Hell, so extinguish it with water.
