Sahih Bukhari · Hadith 2279

حدثنا مسدد، حدثنا يزيد بن زريع، عن خالد، عن عكرمة، عن ابن عباس رضى الله عنهما قال احتجم النبي صلى الله عليه وسلم وأعطى الحجام أجره، ولو علم كراهية لم يعطه‏.‏

Narrated Ibn `Abbas: When the Prophet was cupped, he paid the man who cupped him his wages. If it had been undesirable he would not have paid him.
