question #1 Sahih al-Bukhari 2086, Book 34, Hadith 39 : What professions and practices are prohibited in Islam according to the teachings of the Prophet Muhammad (ﷺ)?

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 (ﷺ) 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.”
