God's Prophet (a.s) said: “An angel saw a man standing at the door of a house, and asked: “O' Servant of God! Why are you standing here?” The man replied: “I know a believing brother in this house, and I am waiting for him to come out and greet him.” The angel asked: “Are you his relative, or do you need something?” He replied: “I do not need anything. I have made a pact of brotherhood with him in the way of God. Besides being Muslims, we have no close ties.” The angel said: “I am sent to you from God. He greets you and says: “You have indeed come to visit Me. Now I will grant entrance to Heaven to you, and save you from the Fire of Hell for your love for Me.”
