Iron

Ar-Ra‘d 13:5

۞ وَإِن تَعۡجَبۡ فَعَجَبٞ قَوۡلُهُمۡ أَءِذَا كُنَّا تُرَٰبًا أَءِنَّا لَفِي خَلۡقٖ جَدِيدٍۗ أُوْلَٰٓئِكَ ٱلَّذِينَ كَفَرُواْ بِرَبِّهِمۡۖ وَأُوْلَٰٓئِكَ ٱلۡأَغۡلَٰلُ فِيٓ أَعۡنَاقِهِمۡۖ وَأُوْلَٰٓئِكَ أَصۡحَٰبُ ٱلنَّارِۖ هُمۡ فِيهَا خَٰلِدُونَ ٥

And if you are astonished, [O Muhammad] - then astonishing is their saying, "When we are dust, will we indeed be [brought] into a new creation?" Those are the ones who have disbelieved in their Lord, and those will have shackles upon their necks, and those are the companions of the Fire; they will abide therein eternally.

Al-Isrā’ 17:50

۞ قُلۡ كُونُواْ حِجَارَةً أَوۡ حَدِيدًا ٥٠

Say, "Be you stones or iron

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-Ḥajj 22:21

وَلَهُم مَّقَٰمِعُ مِنۡ حَدِيدٖ ٢١

And for [striking] them are maces of iron.

Saba’ 34:10

۞ وَلَقَدۡ ءَاتَيۡنَا دَاوُۥدَ مِنَّا فَضۡلٗاۖ يَٰجِبَالُ أَوِّبِي مَعَهُۥ وَٱلطَّيۡرَۖ وَأَلَنَّا لَهُ ٱلۡحَدِيدَ ١٠

And We certainly gave David from Us bounty. [We said], "O mountains, repeat [Our] praises with him, and the birds [as well]." And We made pliable for him iron,

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.
