(Iron: The Most Useful Metal)
57:25We sent our messengers supported by clear proofs, and we sent down to them the scripture and the law, that the people may uphold justice. And we sent down the iron, wherein there is strength, and many benefits for the people. All this in order for God to distinguish those who would support Him and His messengers, on faith. God is Powerful, Almighty.
لَقَد أَرسَلنا رُسُلَنا بِالبَيِّنٰتِ وَأَنزَلنا مَعَهُمُ الكِتٰبَ وَالميزانَ لِيَقومَ النّاسُ بِالقِسطِ وَأَنزَلنَا الحَديدَ فيهِ بَأسٌ شَديدٌ وَمَنٰفِعُ لِلنّاسِ وَلِيَعلَمَ اللَّهُ مَن يَنصُرُهُ وَرُسُلَهُ بِالغَيبِ إِنَّ اللَّهَ قَوِىٌّ عَزيزٌ
