When in the battle of OHUD the prophet's tooth was knocked out of his mouth, and his forehead was injured, and muslims were defeated; the Messenger of God became very anxious about the polytheists and idolaters, thinking how could they be guided while doing so with their apostle?!
He said: ``How can a people like these prosper when they do such and such to their apostle who calls them to their Lord!'' This verse revealed to give consolation to the apostle.
