Overall meaning :
We have sent Our messengers with manifest signs and proofs, and We have sent down with them the scriptures and justice, so that people may conduct themselves with fairness. We have sent down iron, with its great might in which there is material for war and various benefits for mankind, so that Allah may show people what He already knows about them, according to his foreknowledge, who utilizes iron weapons to support His religion and His messengers without even having seen Him. Allah is All-Strong, All-Mighty: nothing whatsoever can ever frustrate His purpose, and His power can by no means be overcome or resisted.

As for monastic asceticism, We did not prescribe it for them; rather, they invented it themselves, seeking thereby Allah’s good pleasure; but then they did not observe it as it should have been observed; and so We granted those of them who believed their due reward, but many of them were rebellious transgressors who disobeyed My commands!
