The word(s) "mount" appears 84 time(s) in 77 verse(s) in Quran in Mohsin Khan translation.

(41) Is not He (better than your gods) Who has made the earth as a fixed abode, and has placed rivers in its midst, and has placed firm mountains therein, and has set a barrier between the two seas (of salt and sweet water)? Is there any ilah (god) with Allah? Nay, but most of them know not!

(42) And you will see the mountains and think them solid, but they shall pass away as the passing away of the clouds. The Work of Allah, Who perfected all things, verily He is Well-Acquainted with what you do.

(43) Then, when Musa (Moses) had fulfilled the term, and was travelling with his family, he saw a fire in the direction of Tur (mount). He said to his family: "Wait, I have seen a fire; perhaps I may bring you from there some information, or a burning fire-brand that you may warm yourselves."

(44) And you (O Muhammad صلى الله عليه وسلم) were not on the western side (of the mount), when We made clear to Musa (Moses) the commandment, and you were not among the witnesses.

(45) And you (O Muhammad صلى الله عليه وسلم) were not at the side of the Tur (mount) when We did call: [it is said that Allah called the followers of Muhammad صلى الله عليه وسلم, and they answered His Call, or that Allah called Musa (Moses)]. But (you are sent) as a mercy from your Lord, to give warning to a people to whom no warner had come before you: in order that they may remember or receive admonition. [Tafsir At-Tabari].

(46) He said: "This has been given to me only because of the knowledge I possess." Did he not know that Allah had destroyed before him generations, men who were stronger than him in might and greater in the amount (of riches) they had collected? But the Mujrimun (criminals, disbelievers, polytheists, sinners) will not be questioned of their sins (because Allah knows them well, so they will be punished without being called to account).

(47) He has created the heavens without any pillars that you see, and has set on the earth firm mountains lest it should shake with you. And He has scattered therein moving (living) creatures of all kinds. And We send down water (rain) from the sky, and We cause (plants) of every goodly kind to grow therein.

(48) And when a wave covers them like shades (i.e. like clouds or the mountains of sea-water), they invoke Allah, making their invocations for Him only. But when He brings them safe to land, there are among them those that stop in between (Belief and disbelief). But none denies Our Signs except every perfidious ingrate.

(49) Truly, We did offer Al-Amanah (the trust or moral responsibility or honesty and all the duties which Allah has ordained) to the heavens and the earth, and the mountains, but they declined to bear it and were afraid of it (i.e. afraid of Allah's Torment). But man bore it. Verily, he was unjust (to himself) and ignorant (of its results).

(50) 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."
