The word(s) "iron" appears 11 time(s) in 10 verse(s) in Quran in Mohsin Khan translation.

(1) And if you (O Muhammad صلى الله عليه و سلم) wonder (at these polytheists who deny your message of Islamic Monotheism and have taken besides Allah others for worship who can neither harm nor benefit), then wondrous is their saying: "When we are dust, shall we indeed then be (raised) in a new creation?" They are those who disbelieved in their Lord! They are those who will have iron chains tying their hands to their necks. They will be the dwellers of the Fire to abide therein.

(2) Say (O Muhammad صلى الله عليه و سلم) "Be you stones or iron,"

(3) "Give me pieces (blocks) of iron;" then, when he had filled up the gap between the two mountain-cliffs, he said: "Blow;" then when he had made them (red as) fire, he said: "Bring me molten copper to pour over them."

(4) And for them are hooked rods of iron (to punish them).

(5) And indeed We bestowed grace on Dawud (David) from Us (saying): "O you mountains. Glorify (Allah) with him! And you birds (also)! And We made the iron soft for him."

(6) Those who were deemed weak will say to those who were arrogant: "Nay, but it was your plotting by night and day: when you ordered us to disbelieve in Allah and set up rivals to Him!" And each of them (parties) will conceal their own regrets (for disobeying Allah during this worldly life), when they behold the torment. And We shall put iron collars round the necks of those who disbelieved. Are they requited aught except what they used to do?

(7) Verily We have put on their necks iron collars reaching to the chins, so that their heads are raised up.

(8) When iron collars will be rounded over their necks, and the chains, they shall be dragged along,

(9) Indeed We have sent Our Messengers with clear proofs, and revealed with them the Scripture and the Balance (justice) that mankind may keep up justice. And We brought forth iron wherein is mighty power (in matters of war ), as well as many benefits for mankind, that Allah may test who it is that will help Him (His religion) and His Messengers in the unseen. Verily, Allah is All-Strong, All-Mighty.

(10) Verily, We have prepared for the disbelievers iron chains, iron collars, and a blazing Fire.
