I heard the Prophet ﷺ saying, "If there is any healing in your medicines, then it is in cupping, a gulp of honey or branding with fire (cauterization) that suits the ailment, but I don't like to be (cauterized) branded with fire."  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ إِنْ كَانَ فِي شَىْءٍ مِنْ أَدْوِيَتِكُمْ أَوْ يَكُونُ فِي شَىْءٍ مِنْ أَدْوِيَتِكُمْ خَيْرٌ فَفِي شَرْطَةِ مِحْجَمٍ أَوْ شَرْبَةِ عَسَلٍ أَوْ لَذْعَةٍ بِنَارٍ تُوَافِقُ الدَّاءَ وَمَا أُحِبُّ أَنْ أَكْتَوِيَ  

When the Prophet ﷺ was cupped, he paid the man who cupped him his wages.  

احْتَجَمَ النَّبِيُّ ﷺ وَأَعْطَى الْحَجَّامَ أَجْرَهُ  

The Prophet ﷺ used to get cupped and would never withhold the wages of any person .  

سَمِعْتُ أَنَسًا ؓ يَقُولُ كَانَ النَّبِيُّ ﷺ يَحْتَجِمُ وَلَمْ يَكُنْ يَظْلِمُ أَحَدًا أَجْرَهُ  

The Prophet ﷺ said, "Fever is from the heat of the (Hell) Fire, so cool it with water."  

عَنِ النَّبِيِّ ﷺ قَالَ الْحُمَّى مِنْ فَيْحِ جَهَنَّمَ فَأَبْرِدُوهَا بِالْمَاءِ  

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  

I heard Messenger of Allah ﷺ saying, "Fever is from the heat of Hell, so abate fever with water."  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ الْحُمَّى مِنْ فَوْحِ جَهَنَّمَ فَابْرُدُوهَا بِالْمَاءِ
