[Machine] I went with my father as a young boy to the Prophet ﷺ. My father said to him, "I am a physician, so show me this merchandise that is on your back." He (the Prophet) said, "What will you do with it?" He (my father) said, "I will cut it." He (the Prophet) said, "You are not a physician, but rather you are the companion of the physician who created it and placed it. He (the Prophet) said something else."
