If a wound or killing struck you—O believers—in the battle of —Uhud— so you were sad for that, then a wound and killing like that had surely struck the polytheists in the battle of —Badr—. And those days Allah rotates them between the people, victory once and defeat another, for what is in that of the wisdom, until what Allah known in eternity appears so that Allah distinguishes the truthful believer from others, and honors groups from you with martyrdom. And Allah does not love those who wronged themselves, and sat back from fighting in His cause.
