The word(s) "wall" appears 18 time(s) in 18 verse(s) in Quran in Saheeh International translation.

(1) And it was said, "O earth, swallow your water, and O sky, withhold [your rain]." And the water subsided, and the matter was accomplished, and the ship came to rest on the [mountain of] Judiyy. And it was said, "Away with the wrongdoing people."

(2) He will gulp it but will hardly [be able to] swallow it. And death will come to him from everywhere, but he is not to die. And before him is a massive punishment.

(3) Then, do those who have planned evil deeds feel secure that Allah will not cause the earth to swallow them or that the punishment will not come upon them from where they do not perceive?

(4) Then do you feel secure that [instead] He will not cause a part of the land to swallow you or send against you a storm of stones? Then you would not find for yourselves an advocate.

(5) And say, "The truth is from your Lord, so whoever wills - let him believe; and whoever wills - let him disbelieve." Indeed, We have prepared for the wrongdoers a fire whose walls will surround them. And if they call for relief, they will be relieved with water like murky oil, which scalds [their] faces. Wretched is the drink, and evil is the resting place.

(6) So they set out, until when they came to the people of a town, they asked its people for food, but they refused to offer them hospitality. And they found therein a wall about to collapse, so al-Khidh r restored it. [Moses] said, "If you wished, you could have taken for it a payment."

(7) And as for the wall, it belonged to two orphan boys in the city, and there was beneath it a treasure for them, and their father had been righteous. So your Lord intended that they reach maturity and extract their treasure, as a mercy from your Lord. And I did it not of my own accord. That is the interpretation of that about which you could not have patience."

(8) Bring me sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper."

(9) And throw what is in your right hand; it will swallow up what they have crafted. What they have crafted is but the trick of a magician, and the magician will not succeed wherever he is."

(10) And We caused the earth to swallow him and his home. And there was for him no company to aid him other than Allah, nor was he of those who [could] defend themselves.
