The belief in the existence of al-Khidr

This is a letter from the questioner, Ali Hamud Mubarak al-Amri, from al-Qunfudhah, in which he says: I believe in Allah alone, who has no partner, but I have heard some people say: There is a man in very white clothes, and no trace of travel is seen on him. This man is called the Green Man. If this man gives you something, the blessing of your wealth increases, and if he stops at a shop, its profit increases. Please inform us whether these matters are reasonable or are they from religious innovations?
Answer: This statement is a false statement with no basis, and this man does not exist. Some people claim that al-Khidr is the one intended by this man, and this is something that has no truth. Al-Khidr died before the Prophet (peace and blessings be upon him) by a period of time, according to the correct opinion of the scholars. This superstition that you mentioned is entirely from the fabrication of Satan and has no basis. You should know that and not be deceived by the statements of these sorcerers. Yes.
