مُوَطَّأُ مَالِكٍ
Muwatta Malik 1729
The Evil Eye
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ إِنَّ الْحُمَّى مِنْ فَيْحِ جَهَنَّمَ فَابْرُدُوهَا بِالْمَاءِ .
Yahya related to me from Malik from Hisham ibn Urwa from his father that the Messenger of Allah, (ﷺ), said, "Fever is from the vehemence of the heat of Jahannam, so cool it with water."
