لَقَد أَرسَلنا رُسُلَنا بِالبَيِّناتِ وَأَنزَلنا مَعَهُمُ الكِتابَ وَالميزانَ لِيَقومَ النّاسُ بِالقِسطِ ۖ وَأَنزَلنَا الحَديدَ فيهِ بَأسٌ شَديدٌ وَمَنافِعُ لِلنّاسِ وَلِيَعلَمَ اللَّهُ مَن يَنصُرُهُ وَرُسُلَهُ بِالغَيبِ ۚ إِنَّ اللَّهَ قَوِيٌّ عَزيزٌ

We sent Our messengers with clear signs, and We sent down with them the Scripture and the Balance, so that people may uphold justice. We also sent down iron, in which is a great strength and benefits for humankind, so that God may distinguish those who support Him and His messengers, although unseen. God is Powerful and Mighty.
