"Narrated 'Aun bin Abu Juhaifa: My father bought a slave who practiced the profession of cupping. (My father broke the slave's instruments of cupping). I asked my father why he had done so. He replied, "The Prophet forbade the acceptance of the price of a dog or blood, and also forbade the profession of tattooing, getting tattooed and receiving or giving Riba, (usury), and cursed the picture-makers.""
