An angel once passed by a man standing at the door of a house. He asked, 'Servant of Allah, what brings you here?' 'My brother lives here,' replied the man, 'I intend to greet him.' 'Is there any blood relation between you or has a need brought you to him?' asked the angel. 'No,' answered the man, 'we are neither related nor has a need brought me to him except our Islamic brotherhood and respect for him. I am acquainted to him and I greet him only for the sake of Allah; the Lord of the worlds.' The angel said, 'I am a messenger of Allah to you and He sends you greetings saying to you: It is in fact I that you have visited and it is I that you have approached; and for that, I have made Paradise mandatory for you, put off My wrath from you and protected you from the Fire (of Hell).
