What is the ruling on some people claiming that they know things about people through observation (firasah) that they did in the past?

Question:
He says: Honorable Shaykh, may Allah grant you success, some people say that they know through observation, and say, "I can tell you about some of the things you did in the past."

Answer:
This is a lie; he is a liar. No one knows the unseen except Allah. No one knows the past except Allah. As for observing that you are intelligent or that you are such-and-such, that is possible, . But if he tells you about the unseen, he is a liar. No one knows the unseen except Allah (Mighty and Majestic). Or if he tells you about the future, he is a liar. Yes.
