I saw my father buying a slave whose profession was cupping, and ordered that his instruments (of cupping) be broken. I asked him the reason for doing so. He replied, “Allah’s Messenger (ﷺ) prohibited taking money for blood, the price of a dog, and the earnings of a slave-girl by prostitution; he cursed her who tattoos and her who gets tattooed, the eater of Riba (usury), and the maker of pictures.”
