In spite of the fact that you (Mohammad) forbade them of secret gathering/ whispering, the hypocrites practice their secret meetings and brag about their sins and disobedience of the prophet of God. When they come to you, they greet you in such a way that even God (who loves you so much) has not greeted you. They jokingly say among themselves: “How come God does not punish us for this?” Hell is an enough punishment for them. They will be used as its fuel. What a terrible place to end up in.
