“I heard the Prophet ﷺ say: ‘Fever is from the heat of the Hell-fire, so cool it down with water.’ He entered upon a son of ‘Ammar and said: ‘Take away the harm, O Lord of mankind, O God of mankind.’”
سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ الْحُمَّى مِنْ فَيْحِ جَهَنَّمَ فَابْرُدُوهَا بِالْمَاءِ فَدَخَلَ عَلَى ابْنٍ لِعَمَّارٍ فَقَالَ اكْشِفِ الْبَاسْ رَبَّ النَّاسْ إِلَهَ النَّاسْ
