How can an ordinary person distinguish between the miracles of the prophets and the wonders of sorcerers, such as Abraham's survival from the fire, and some sorcerers entering fire without their bodies being affected, and devils informing Musaylimah the Liar and Al-Aswad Al-Ansi of some unseen matters, and the extraordinary feats of Al-Harith Al-Dimashqi, which include his leg coming out of shackles, preventing weapons from penetrating him, people seeing men in the air, and a marble slab glorifying God in his hand, knowing that these matters resemble some of the prophets' miracles, such as Allah's saying: "Say, 'None in the heavens and earth knows the unseen except Allah,'" and "And We made the iron pliable for him"?

What the questioner mentioned about Musaylima the Liar and Al-Harith al-Dimashqi is taken from Sheikh al-Islam’s treatise "Al-Furqan bayna Awliya' al-Rahman wa Awliya' al-Shaytan" (The Criterion between the Friends of the Most Merciful and the Friends of Satan). The rest of the passage explains that satanic states vanish with the mention of Allah. An example of this is that the spear did not penetrate Al-Harith al-Dimashqi until Allah’s name was uttered, at which point he was killed. Sheikh al-Islam advised reading this entire treatise. For further understanding, one can read Ibn Taymiyyah’s book "Al-Nubuwwat" (The Prophecies) to learn the difference between a prophet and a false prophet, the methods of proving prophethood, and refuting opponents.
