Are circus performances considered sorcery or visual illusions?

Question:
There are places called circuses where some people walk on thin ropes and walk on hot coals. Is this considered sorcery, or is it considered visual illusions?

Answer:
No, this is not sorcery. They do things that make people think they are real, but they are lies. He walks next to the hot coals and makes them think he is walking on them. This is deceiving people.
In the view of the Shaykh al-Islam Ibn Taymiyyah, regarding the Batayhiyyah who make people think they walk on hot coals, he said: "Come, I will wash my feet, and you wash your feet, and we will walk on the hot coals." They said: "No," because they anoint their feet with fats that prevent the heat of the coals from reaching their feet.
He (may Allah have mercy on him) alerted them to this and invalidated their trickery. He said: "Come, let us wash our feet with water and walk on the hot coals." They said: "No," and they were exposed with him.
