Metallurgy

أَنزَلَ مِنَ ٱلسَّمَآءِ مَآءً فَسَالَتْ أَوْدِيَةٌۢ بِقَدَرِهَا فَٱحْتَمَلَ ٱلسَّيْلُ زَبَدًا رَّابِيًا ۚ وَمِمَّا يُوقِدُونَ عَلَيْهِ فِى ٱلنَّارِ ٱبْتِغَآءَ حِلْيَةٍ أَوْ مَتَـٰعٍ زَبَدٌ مِّثْلُهُۥ ۚ كَذَٰلِكَ يَضْرِبُ ٱللَّهُ ٱلْحَقَّ وَٱلْبَـٰطِلَ ۚ فَأَمَّا ٱلزَّبَدُ فَيَذْهَبُ جُفَآءً ۖ وَأَمَّا مَا يَنفَعُ ٱلنَّاسَ فَيَمْكُثُ فِى ٱلْأَرْضِ ۚ كَذَٰلِكَ يَضْرِبُ ٱللَّهُ ٱلْأَمْثَالَ

He sends water from the sky that fills riverbeds to overflowing, each according to its measure. The stream carries on its surface a growing layer of froth, like the froth that appears when people melt metals in the fire to make ornaments and tools: in this way God illustrates truth and falsehood- the froth disappears, but what is of benefit to man stays behind- this is how God makes illustrations.

ءَاتُونِى زُبَرَ ٱلْحَدِيدِ ۖ حَتَّىٰٓ إِذَا سَاوَىٰ بَيْنَ ٱلصَّدَفَيْنِ قَالَ ٱنفُخُوا۟ ۖ حَتَّىٰٓ إِذَا جَعَلَهُۥ نَارًا قَالَ ءَاتُونِىٓ أُفْرِغْ عَلَيْهِ قِطْرًا

bring me lumps of iron!’ and then, when he had filled the gap between the two mountainsides [he said], ‘Work your bellows!’ and then, when he had made it glow like fire, he said, ‘Bring me molten metal to pour over it!’

فَمَا ٱسْطَـٰعُوٓا۟ أَن يَظْهَرُوهُ وَمَا ٱسْتَطَـٰعُوا۟ لَهُۥ نَقْبًا

Their enemies could not scale the barrier, nor could they pierce it,

يَعْلَمُ مَا يَلِجُ فِى ٱلْأَرْضِ وَمَا يَخْرُجُ مِنْهَا وَمَا يَنزِلُ مِنَ ٱلسَّمَآءِ وَمَا يَعْرُجُ فِيهَا ۚ وَهُوَ ٱلرَّحِيمُ ٱلْغَفُورُ

He knows all that goes into the earth and all that comes out of it; He knows all that comes down from the heavens and all that goes up to them. He is the Merciful, the Forgiving.

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 sent Our messengers with clear signs, the Scripture and the Balance, so that people could uphold justice: We also sent iron, with its mighty strength and many uses for mankind, so that God could mark out those who would help Him and His messengers though they cannot see Him. Truly God is powerful, almighty.
