Indeed We have sent Our Messengers with clear proofs, and revealed with them the Scripture and the Balance (justice) that mankind may keep up justice. And We brought forth iron wherein is mighty power (in matters of war1), as well as many benefits for mankind, that Allâh may test who it is that will help Him (His religion) and His Messengers in the unseen. Verily, Allâh is All-Strong, All-Mighty.
