Indeed, We have sent Our messengers before with clear proofs and sent down with them the Book (the Scripture) and the balance (between right and wrong), that men may stand together in justice: And We sent down iron, in which is (material for) power and might (in war), as well as many benefits for mankind, that Allah may test who are those who will help Him (and His Religion), the Unseen and His messengers: Surely, Allah is Full of Strength (Qhavi), exalted in Might (Aziz, and able to enforce His Will).
