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

(11) And We made the people who were deemed weak to inherit the eastern lands and the western ones which We had blessed; and the good word of your Lord was fulfilled in the children of Israel because they bore up (sufferings) patiently; and We utterly destroyed what Firon and his people had wrought and what they built.

(12) And when We delivered you from Firon's people who subjected you to severe torment, killing your sons and sparing your women, and in this there was a great trial from your Lord.

(13) In the manner of the people of Firon and those before them; they disbelieved in Allah's communications, therefore Allah destroyed them on account of their faults; surely Allah is strong, severe in requiting (evil).

(14) In the manner of the people of Firon and those before them; they rejected the communications of their Lord, therefore We destroyed them on account of their faults and We drowned Firon's people, and they were all unjust.

(15) Then did We send up after them Musa and Haroun to Firon and his chiefs with Our signs, but they showed pride and they were a guilty people.

(16) And Firon said: Bring to me every skillful magician.

(17) But none believed in Musa except the offspring of his people, on account of the fear of Firon and their chiefs, lest he should persecute them; and most surely Firon was lofty in the land; and most surely he was of the extravagant.

(18) And Musa said: Our Lord! surely Thou hast given to Firon and his chiefs finery and riches in this world's life, to this end, our Lord, that they lead (people) astray from Thy way: Our Lord! destroy their riches and harden their hearts so that they believe not until they see the painful punishment.

(19) And We made the children of Israel to pass through the sea, then Firon and his hosts followed them for oppression and tyranny; until when drowning overtook him, he said: I believe that there is no god but He in Whom the children of Israel believe and I am of those who submit.

(20) To Firon and his chiefs, but they followed the bidding of Firon, and Firon's bidding was not right-directing.
