The Messenger of Allah ﷺ was cupped, and he never withheld anyone's wages unjustly.
حدثنا وكيع عن مسعر عن عمرو بن عامر قال سمعت
احتجم رسول الله ﷺ وكان لا يظلم أحدا أجرا
Its isnad is sahih. Amr bin Amir Ansari Kufi is trustworthy. Bukhari related the hadith in 3/324, no. 2102, in Fath al-Bari, in the Book of Sales, mention of the cupper, and Muslim in 4/1732, no. 1577, in the Book of Greetings, "For every ailment there is a remedy". See also what preceded at 12013.
