There is a Persian expression that goes like
this: “Guests are Friends of God”. This reflects the way Iranian culture
threats guests. It also implies that God has friends. I wonder if God has
enemies as well, i.e. Satan. Accordingly, anyone who believes in God and
after-life rewards and punishments promises, such person needs to take a good
care of his or her guests in order to receive favorable recommendation. As we
know, any dealing with God is reciprocal, which is another story in its own
merit.
