The hypocrites held themselves back and took no part in the defensive battle of Ohud, but when the war was over and Muslims troops returened home, they started reproaching them with baseless sayings; that if you had obeyed us and stayed here with us, none of you would have been killed.
QURÄN, gives them a knocking down answer, here in this verse that, if what you say is right, then avert and turn away the death from yourselves, i.e. By saying so, you pretend to know the unseen, and can foretell your destiny in future! If so, keep aloof of death.
In this verse the believers are called `BROTHERS' while they are never the brothers to the hypocrites. This implies ironically that you pretend to be Muslims, but keep your brothers in self-sacrifice without giving them a hand.
