How do I know whom to sit with and take knowledge from?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: What is the way to know whom I should sit with, and whether he has any doubtful matters or deviant thought?

Answer:
Ask the people who have experience with him, and also look at his words and actions. Ask those who know him. As for an unknown person about whom you know nothing, do not take the risk and go with him until you are certain of his knowledge and his religion, and certain that he acts upon his knowledge. May Allah reward you. This knowledge is religion, so look to whom you are taking your religion from.
Do not take knowledge from just anyone. Look first, and if you trust him, then take knowledge from him. Especially in this time, first, the ignorant and the claimants of knowledge who have no knowledge have increased, and they misguide and are misguided, as the Prophet (peace and blessings be upon him) said. Second, the callers to evil have increased. The callers to evil have increased now, so may Allah increase them, and one must be very cautious, the student of knowledge, and he must be careful and verify matters regarding those from whom he wants to take knowledge. The one who studies, if he studies in a public place, then if he makes a mistake it will be exposed. But the problem is the one who studies in a secret place, about whom no one knows. This is the problem, so beware of secret places. Yes.
