﴿ لَقَدْ أَرْسَلْنَا رُسُلَنَا بِٱلْبَيِّنَٰتِ وَأَنزَلْنَا مَعَهُمُ ٱلْكِتَٰبَ وَٱلْمِيزَانَ لِيَقُومَ ٱلنَّاسُ بِٱلْقِسْطِ ۖ وَأَنزَلْنَا ٱلْحَدِيدَ فِيهِ بَأْسٌۭ شَدِيدٌۭ وَمَنَٰفِعُ لِلنَّاسِ وَلِيَعْلَمَ ٱللَّهُ مَن يَنصُرُهُۥ وَرُسُلَهُۥ بِٱلْغَيْبِ ۚ إِنَّ ٱللَّهَ قَوِىٌّ عَزِيزٌۭ ﴾

“Indeed, [even aforetime] did We send forth Our apostles with all evidence of [this] truth; and through them We bestowed revelation from on high, and [thus gave you] a balance [wherewith to weigh right and wrong], so that men might behave with equity; and We bestowed [upon you] from on high [the ability to make use of] iron, in which there is awesome power as well as [a source of] benefits for man: and [all this was given to you] so that God might mark out those who would stand up for him and His Apostle, even though He [Himself] is beyond the reach of human perception. Verily, God is powerful, almighty!”

(We verily sent Our messengers with clear proofs) with commands, prohibitions and signs, (and revealed with them the Scripture) and sent to them Gabriel with the Scripture (and the Balance) expositing there in justice, (that mankind may observe right measure) justice; (and He revealed iron) We created iron, (wherein is mighty power) such that only fire makes it pliable; it is also said that this means: there is in it mighty strength for fighting and war (and (many) uses for mankind) they use it to make things like knives, axes, files and other things, (and that Allah may know) in order that Allah may see (him who helpeth Him and His messengers, though unseen) by means of these weapons. (Lo! Allah is Strong) by helping His friends, (Almighty) in retribution against His enemies.
