Sayyidina Ikrimah reported that Sayyidina Ibn Abbas (RA) had three slaves who were cuppers, two of them on remuneration and one attended to him and his family. He also reported that Ibn Abbas (RA) cited the Prophet (SAW) as saying, “How excellent a cupper is! He removes blood and lightens the back and sharpens vision.” He also reported that when Allah’s Messenger (SAW) was on Mi’raj, he did not go by any group of angels without their advising him to resort to cupping. He said, “The best cupping you can have is on the 17th, 19th and 21st.” He said also, “The best medicine you treat yourself with is Sa’ut, Ladud, cupping and purgative.” Indeed, Allah’s Messenger was given medicine by Abbas (RA) and his sahabah, who poured medicine in his mouth. So he asked, ‘Who has treated with ladud? Let them all pour it in their mouth.” So no one in the house was spared but medicine was poured in his mouth, except his uncle Abbas. Nadr explained that ladud is Wajur.
