Verily We sent Our Messengers with clear Signs and We sent down with them the Book and the Balance of Justice so that people may grow firm and stable in justice. And (of minerals) We brought forth iron in which is fierce force (for weapons and defence) and which has (multiple other) benefits for people (in industrial development). And (the purpose is) that Allah may bring to light who helps Him and His Messengers (i.e. Din [Religion of Islam]) without seeing. Surely Allah is (Himself) the All-Powerful, the Almighty.
