1. My father (rah) said: it was narrated to me by Sa’d b. Abdillah from Ahmad b. Muhammad from al-Hassan b. Mahbub from Abi Jameela from Abi Ja’far al-Baqir (a.s.) who said: "that an angel passed by a person standing near a door. The angel asked him, “O servant of Allah! Why are you standing here?” He replied, “One of my believing brothers lives here. I want to salute him.” The angel asked, “Is he your near relative or you are having some work with him?” He replied, “He is neither a near relative of mine nor do I have any work with him. He is just a Muslim brother for me and hence, I have come to pay respect to him. I have made it obligatory on myself to salute him for the sake of pleasure of the Lord of the worlds.” The angel said, “Allah has sent me to you to convey His salutations and has said: Your only aim was to please Me and you met Me. I have made Paradise obligatory for you, given you salvation from My anger so that you are granted freedom from the fire of Hell."
