Whenever a lady suffering from fever was brought to Asma' bint Abu Bakr, she used to invoke Allah for her and then sprinkle some water on her body, at the chest and say, "Messenger of Allah ﷺ used to order us to abate fever with water."  

أَنَّ أَسْمَاءَ بِنْتَ أَبِي بَكْرٍ ؓ كَانَتْ إِذَا أُتِيَتْ بِالْمَرْأَةِ قَدْ حُمَّتْ تَدْعُو لَهَا أَخَذَتِ الْمَاءَ فَصَبَّتْهُ بَيْنَهَا وَبَيْنَ جَيْبِهَا قَالَتْ وَكَانَ رَسُولُ اللَّهِ ﷺ يَأْمُرُنَا أَنْ نَبْرُدَهَا 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 ﷺ ordered us to cool it with water."  

أَنَّ أَسْمَاءَ بِنْتَ أَبِي بَكْرٍ كَانَتْ إِذَا أُتِيَتْ بِالْمَرْأَةِ وَقَدْ حُمَّتْ تَدْعُو لَهَا أَخَذَتِ الْمَاءَ فَصَبَّتْهُ بَيْنَهَا وَبَيْنَ جَيْبِهَا وَقَالَتْ إِنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَأْمُرُنَا أَنْ نُبْرِدَهَا بِالْمَاءِ  

[Machine] "When Asmaa was brought a woman, she would pour water between herself and her side and say: 'Indeed, the Messenger of Allah ﷺ commanded us to cool it with water.'"  

أَنَّ أَسْمَاءَ كَانَتْ إِذَا أُتِيَتْ بِالْمَرْأَةِ قَدْ حُمَّتْ تَدْعُو لَهَا أَخَذَتِ الْمَاءَ فَتَصُبُّ بَيْنَهَا وَبَيْنَ جَنْبِهَا وَقَالَتْ «إِنَّ رَسُولَ اللهِ ﷺ كَانَ يَأْمُرُنَا أَنْ نُبْرِدَهَا بِالْمَاءِ»  

[Machine] "That the name of the daughter of Abu Bakr used to be brought to the menstruating woman, so she would invoke blessings upon her and she would take water and pour it between her and her side, and she said, 'Verily, the Messenger of Allah ﷺ commanded her to cool it with water.'"  

أَنَّ أَسْمَاءَ بِنْتِ أَبِي بَكْرٍ كَانَتْ تُؤْتَى بِالْمَرْأَةِ الْمَوْعُوكَةِ قَدْ حُمَّتْ تَدْعُو لَهَا أَخَذْتِ الْمَاءَ فَصَبَّتْهُ بَيْنَهَا وَبَيْنَ جَنْبِهَا وَقَالَتْ «إِنَّ رَسُولَ اللهِ ﷺ أَمَرَهَا أَنْ تُبْرِدَهَا بِالْمَاءِ»
