The Prophet ﷺ sent for a slave who had the profession of cupping, and he cupped him. The Prophet ﷺ ordered that he be paid one or two Sas, or one or two Mudds of foodstuff, and appealed to his masters to reduce his taxes:  

دَعَا النَّبِيُّ ﷺ غُلاَمًا حَجَّامًا فَحَجَمَهُ وَأَمَرَ لَهُ بِصَاعٍ أَوْ صَاعَيْنِ أَوْ مُدٍّ أَوْ مُدَّيْنِ وَكَلَّمَ فِيهِ فَخُفِّفَ مِنْ ضَرِيبَتِهِ
