The word(s) "mountain" appears 61 time(s) in 56 verse(s) in Quran in Mohsin Khan translation.

(31) 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.

(32) 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).

(33) 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."

(34) See you not that Allah sends down water (rain) from the sky, and We produce therewith fruits of various colours, and among the mountains are streaks white and red, of varying colours and (others) very black.

(35) Then ask them (i.e. these polytheists, O Muhammad صلى الله عليه وسلم): "Are they stronger as creation, or those (others like the heavens and the earth and the mountains) whom We have created?" Verily, We created them of a sticky clay.

(36) Verily, We made the mountains to glorify Our Praises with him [Dawud (David)] in the 'Ashi (i.e. after the mid-day till sunset) and Ishraq (i.e. after the sunrise till mid-day).

(37) He placed therein (i.e. the earth) firm mountains from above it, and He blessed it, and measured therein its sustenance (for its dwellers) in four Days equal (i.e. all these four days were equal in the length of time) for all those who ask (about its creation).

(38) And among His Signs are the ships in the sea like mountains.

(39) And the earth! We have spread it out, and set thereon mountains standing firm, and have produced therein every kind of lovely growth (plants).

(40) And the mountains will move away with a (horrible) movement.
