O you who have believed, do not be as the ones who have disbelieved and have said to their brethren when they strike in the earth (i.e. journey in the land) or are upon expeditions, "If they had been in our presence, they would not have died and not been killed." that (is so that) Allah may make that a regret in their hearts. And Allah gives life and makes to die, and Allah is Ever-Beholding of whatever you do.
