The word(s) "iron" appears 84 time(s) in 77 verse(s) in Quran in Muhammad Habib Shakir translation.

(51) And Firon said: O chiefs! I do not know of any god for you besides myself; therefore kindle a fire for me, O Haman, for brick, then prepare for me a lofty building so that I may obtain knowledge of Musa's god, and most surely I think him to be one of the liars.

(52) And (We destroyed) Qaroun and Firon and Haman; and certainly Musa came to them with clear arguments, but they behaved haughtily in the land; yet they could not outstrip (Us).

(53) And certainly We gave to Dawood excellence from Us: O mountains! sing praises with him, and the birds; and We made the iron pliant to him,

(54) The people of Nuh and Ad, and Firon, the lord of spikes, rejected (apostles) before them.

(55) To Firon and Haman and Qaroun, but they said: A lying magician.

(56) And Firon said: Let me alone that I may slay Musa and let him call upon his Lord; surely I fear that he will change your religion or that he will make mischief to appear in the land.

(57) And a believing man of Firon's people who hid his faith said: What! will you slay a man because he says: My Lord is Allah, and indeed he has brought to you clear arguments from your Lord? And if he be a liar, on him will be his lie, and if he be truthful, there will befall you some of that which he threatens you (with); surely Allah does not guide him who is extravagant, a liar:

(58) O my people! yours is the kingdom this day, being masters in the land, but who will help us against the punishment of Allah if it come to us? Firon said: I do not show you aught but that which I see (myself), and I do not make you follow any but the right way.

(59) And Firon said: O Haman! build for me a tower that I may attain the means of access,

(60) The means of access to the heavens, then reach the god of Musa, and I surely think him to be a liar. And thus the evil of his deed was made fairseeming to Firon, and he was turned away from the way; and the struggle of Firon was not (to end) in aught but destruction.
