Al-Hadid 57:25
لَقَدْ أَرْسَلْنَا رُسُلَنَا بِٱلْبَيِّنَـٰتِ وَأَنزَلْنَا مَعَهُمُ ٱلْكِتَـٰبَ وَٱلْمِيزَانَ لِيَقُومَ ٱلنَّاسُ بِٱلْقِسْطِ ۖ وَأَنزَلْنَا ٱلْحَدِيدَ فِيهِ بَأْسٌ شَدِيدٌ وَمَنَـٰفِعُ لِلنَّاسِ وَلِيَعْلَمَ ٱللَّهُ مَن يَنصُرُهُۥ وَرُسُلَهُۥ بِٱلْغَيْبِ ۚ إِنَّ ٱللَّهَ قَوِىٌّ عَزِيزٌ

We have already sent Our messengers with clear evidences and sent down with them the Scripture and the balance that the people may maintain [their affairs] in justice. And We sent down iron, wherein is great military might and benefits for the people, and so that Allāh may make evident those who support Him and His messengers unseen. Indeed, Allāh is Powerful and Exalted in Might.
We have indeed sent Our messengers with clear proofs, and sent down with them the Book and the Balance, so that people may uphold equity. And We sent down iron in which there is strong power, and benefits for the people; and (We did it) so that Allah knows the one who helps Him and His messengers without seeing (Him). Surely Allah is Strong, Mighty.
