Muwatta Malik #1852
The Evil Eye
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ فَاطِمَةَ بِنْتِ الْمُنْذِرِ، أَنَّ أَسْمَاءَ بِنْتَ أَبِي بَكْرٍ، كَانَتْ إِذَا أُتِيَتْ بِالْمَرْأَةِ وَقَدْ حُمَّتْ تَدْعُو لَهَا أَخَذَتِ الْمَاءَ فَصَبَّتْهُ بَيْنَهَا وَبَيْنَ جَيْبِهَا وَقَالَتْ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يَأْمُرُنَا أَنْ نُبْرِدَهَا بِالْمَاءِ .
Yahya related to me from Malik from Hisham ibn Urwa from Fatima
bint al-Mundhir that whenever a woman who had a fever, was brought to
Asma bint Abi Bakr, she made dua for her and took water and poured it
inside her collar. She said, "The Messenger of Allah, may Allah bless
him and grant him peace, ordered us to cool it with water."
