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 a woman used to come to her (Aisha) to seek her supplication, she poured water between her and her garment, and said: 'The Messenger of Allah ﷺ ordered us to cool it with water, as it is from the heat of Hellfire.'"  

أَنَّهَا كَانَتْ إِذَا أُتِيَتْ بِالْمَرْأَةِ لِتَدْعُوَ لَهَا صَبَّتِ الْمَاءَ بَيْنَهَا وَبَيْنَ جَيْبِهَا وَقَالَتْ إِنَّ رَسُولَ اللهِ ﷺ أَمَرَنَا أَنْ نُبْرِدَهَا بِالْمَاءِ وَقَالَ إِنَّهَا مِنْ فَيْحِ جَهَنَّمَ  

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." (Using translation from Bukhārī 5724)   

أَنَّ أَسْمَاءَ بِنْتَ أَبِي بَكْرٍ كَانَتْ إِذَا أُتِيَتْ بِالْمَرْأَةِ قَدْ حُمَّتْ أَخَذَتْ الْمَاءَ فَنَضَحَتْ بَيْنَهَا وَبَيْنَ جَيْبِهَا وَقَالَتْ إِنَّ رَسُولَ اللهِ ﷺ كَانَ يَأْمُرُنَا أَنْ نُبْرِدَهَا بِالْمَاءِ
