Metallurgy

Al-Kahf 18:96

ءَاتُونِي زُبَرَ ٱلۡحَدِيدِۖ حَتَّىٰٓ إِذَا سَاوَىٰ بَيۡنَ ٱلصَّدَفَيۡنِ قَالَ ٱنفُخُواْۖ حَتَّىٰٓ إِذَا جَعَلَهُۥ نَارٗا قَالَ ءَاتُونِيٓ أُفۡرِغۡ عَلَيۡهِ قِطۡرٗا ٩٦

Bring me sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper."

Al-Kahf 18:97

فَمَا ٱسۡطَٰعُوٓاْ أَن يَظۡهَرُوهُ وَمَا ٱسۡتَطَٰعُواْ لَهُۥ نَقۡبٗا ٩٧

So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration.

Ar-Ra‘d 13:17

أَنزَلَ مِنَ ٱلسَّمَآءِ مَآءٗ فَسَالَتۡ أَوۡدِيَةُۢ بِقَدَرِهَا فَٱحۡتَمَلَ ٱلسَّيۡلُ زَبَدٗا رَّابِيٗاۖ وَمِمَّا يُوقِدُونَ عَلَيۡهِ فِي ٱلنَّارِ ٱبۡتِغَآءَ حِلۡيَةٍ أَوۡ مَتَٰعٖ زَبَدٞ مِّثۡلُهُۥۚ كَذَٰلِكَ يَضۡرِبُ ٱللَّهُ ٱلۡحَقَّ وَٱلۡبَٰطِلَۚ فَأَمَّا ٱلزَّبَدُ فَيَذۡهَبُ جُفَآءٗۖ وَأَمَّا مَا يَنفَعُ ٱلنَّاسَ فَيَمۡكُثُ فِي ٱلۡأَرۡضِۚ كَذَٰلِكَ يَضۡرِبُ ٱللَّهُ ٱلۡأَمۡثَالَ ١٧

He sends down from the sky, rain, and valleys flow according to their capacity, and the torrent carries a rising foam. And from that [ore] which they heat in the fire, desiring adornments and utensils, is a foam like it. Thus Allah presents [the example of] truth and falsehood. As for the foam, it vanishes, [being] cast off; but as for that which benefits the people, it remains on the earth. Thus does Allah present examples.

Saba’ 34:2

يَعۡلَمُ مَا يَلِجُ فِي ٱلۡأَرۡضِ وَمَا يَخۡرُجُ مِنۡهَا وَمَا يَنزِلُ مِنَ ٱلسَّمَآءِ وَمَا يَعۡرُجُ فِيهَاۚ وَهُوَ ٱلرَّحِيمُ ٱلۡغَفُورُ ٢

He knows what penetrates into the earth and what emerges from it and what descends from the heaven and what ascends therein. And He is the Merciful, the Forgiving.

Al-Ḥadīd 57:25

لَقَدۡ أَرۡسَلۡنَا رُسُلَنَا بِٱلۡبَيِّنَٰتِ وَأَنزَلۡنَا مَعَهُمُ ٱلۡكِتَٰبَ وَٱلۡمِيزَانَ لِيَقُومَ ٱلنَّاسُ بِٱلۡقِسۡطِۖ وَأَنزَلۡنَا ٱلۡحَدِيدَ فِيهِ بَأۡسٞ شَدِيدٞ وَمَنَٰفِعُ لِلنَّاسِ وَلِيَعۡلَمَ ٱللَّهُ مَن يَنصُرُهُۥ وَرُسُلَهُۥ بِٱلۡغَيۡبِۚ إِنَّ ٱللَّهَ قَوِيٌّ عَزِيزٞ ٢٥

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 Allah may make evident those who support Him and His messengers unseen. Indeed, Allah is Powerful and Exalted in Might.
