مُوَطَّأُ مَالِكٍ
Muwatta Malik 1730
The Evil Eye
وَحَدَّثَنِي مَالِكٌ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ الْحُمَّى مِنْ فَيْحِ جَهَنَّمَ فَأَطْفِئُوهَا بِالْمَاءِ .
Malik related to me from Nafi from Ibn Umar that the Messenger of Allah, (ﷺ), said, "Fever is from the vehemence of the heat of Jahannam, so put it out with water."
