what
in Edition Clear Qur'an by Talal Itani / Al-Kahf (The Cave)

18:7We made what is upon the earth an ornament for it, to test them as to which of them is best in conduct.

18:8And We will turn what is on it into barren waste.

18:16“Now that you have withdrawn from them, and from what they worship besides God, take shelter in the cave. And your Lord will unfold His mercy for you, and will set your affair towards ease.”

18:27And recite what was revealed to you from the Book of your Lord. There is no changing His words, and you will find no refuge except in Him.

18:29And say, “The truth is from your Lord. Whoever wills—let him believe. And whoever wills—let him disbelieve”. We have prepared for the unjust a Fire, whose curtains will hem them in. And when they cry for relief, they will be relieved with water like molten brass, which scalds the faces. What a miserable drink, and what a terrible place.

18:31These will have the Gardens of Eden, beneath which rivers flow. Reclining on comfortable furnishings, they will be adorned with bracelets of gold, and will wear green garments of silk and brocade. What a wonderful reward, and what an excellent resting-place.

18:42And ruin closed in on his crops, and so he began wringing his hands over what he had invested in it, as it lays fallen upon its trellises. And he was saying, “I wish I never associated anyone with my Lord.”

18:49And the book will be placed, and you will see the sinners fearful of its contents. And they will say, “Woe to us! What is with this book that leaves nothing, small or big, but it has enumerated it?” They will find everything they had done present. Your Lord does not wrong anyone.

18:55What prevented people from accepting faith, when guidance has come to them, and from seeking their Lord’s forgiveness? Unless they are waiting for the precedent of the ancients to befall them, or to have the punishment come upon them face to face.

18:57Who does greater wrong than he, who, when reminded of his Lord’s revelations, turns away from them, and forgets what his hands have put forward? We have placed coverings over their hearts, lest they understand it, and heaviness in their ears. And if you call them to guidance, they will not be guided, ever.

18:58Your Lord is the Forgiver, Possessor of Mercy. Were He to call them to account for what they have earned, He would have hastened the punishment for them. But they have an appointment from which they will find no escape.

18:64He said, “This is what we were seeking.” And so they turned back retracing their steps.

18:68And how will you endure what you have no knowledge of?”

18:78He said, “This is the parting between you and me. I will tell you the interpretation of what you were unable to endure.

18:82And as for the wall, it belonged to two orphaned boys in the town. Beneath it was a treasure that belonged to them. Their father was a righteous man. Your Lord wanted them to reach their maturity, and then extract their treasure—as a mercy from your Lord. I did not do it of my own accord. This is the interpretation of what you were unable to endure.”

18:91And so it was. We had full knowledge of what he had.

18:93Until, when he reached the point separating the two barriers, he found beside them a people who could barely understand what is said.

18:95He said, “What my Lord has empowered me with is better. But assist me with strength, and I will build between you and them a dam.”
