Does God's knowledge of what is in people's souls contradict some people's claim that there are beings who can read minds?

The knowledge of Allah is one of His essential attributes, and it is complete and encompasses all that was and all that will be. He knows what His creation reveals and what they conceal. This knowledge is exclusive to Allah alone; no one else possesses it, for the Unseen is veiled from humans. As for claiming to read minds, it is a claim to the knowledge of the Unseen, and that is disbelief (kufr).
