The word(s) "mountains" appears 39 time(s) in 37 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) "And remember how He made you inheritors after the 'Ad people and gave you habitations in the land: ye build for yourselves palaces and castles in (open) plains, and carve out homes in the mountains; so bring to remembrance the benefits (ye have received) from Allah, and refrain from evil and mischief on the earth."

(2) So the Ark floated with them on the waves (towering) like mountains, and Noah called out to his son, who had separated himself (from the rest): "O my son! embark with us, and be not with the unbelievers!"

(3) And it is He who spread out the earth, and set thereon mountains standing firm and (flowing) rivers: and fruit of every kind He made in pairs, two and two: He draweth the night as a veil o'er the Day. Behold, verily in these things there are signs for those who consider!

(4) If there were a Qur'an with which mountains were moved, or the earth were cloven asunder, or the dead were made to speak, (this would be the one!) But, truly, the command is with Allah in all things! Do not the Believers know, that, had Allah (so) willed, He could have guided all mankind (to the right)? But the Unbelievers,- never will disaster cease to seize them for their (ill) deeds, or to settle close to their homes, until the promise of Allah come to pass, for, verily, Allah will not fail in His promise.

(5) And the earth We have spread out (like a carpet); set thereon mountains firm and immovable; and produced therein all kinds of things in due balance.

(6) Out of the mountains did they hew (their) edifices, (feeling themselves) secure.

(7) And He has set up on the earth mountains standing firm, lest it should shake with you; and rivers and roads; that ye may guide yourselves;

(8) Nor walk on the earth with insolence: for thou canst not rend the earth asunder, nor reach the mountains in height.

(9) One Day We shall remove the mountains, and thou wilt see the earth as a level stretch, and We shall gather them, all together, nor shall We leave out any one of them.

(10) Until, when he reached (a tract) between two mountains, he found, beneath them, a people who scarcely understood a word.
