A jealous, dangerous man would take everything you tell him to his evil memory, to his evil friends to use later on. That is because such people are connected with the devil. You are talking, but do you know to whom you are talking to? You would be drained if you saw the truth. You are telling those to the devil. Satan appears before you in the form of a person and you are talking to him. You should not talk to them; that is because they would be a trouble for you. But if that person is your friend, if he is a Muslim, he would be happy for you when you tell him about the beautiful things you have. - Harun Yahya
