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."
Muwatta Malik Book 50, Hadith 15
