18:17You would have seen the sun, when it rose, veering away from their cave towards the right, and when it sets, moving away from them to the left, as they lay in the midst of the cave. That was one of God’s wonders. He whom God guides is truly guided; but he whom He misguides, for him you will find no directing friend.

18:19Even so, We awakened them, so that they may ask one another. A speaker among them said, “How long have you stayed?” They said, “We have stayed a day, or part of a day.” They said, “Your Lord knows best how long you have stayed.” “Send one of you to the city, with this money of yours, and let him see which food is most suitable, and let him bring you some provision thereof. And let him be gentle, and let no one become aware of you.”

18:20“If they discover you, they will stone you, or force you back into their religion; then you will never be saved.”

18:22They will say, “Three, and their fourth being their dog.” And they will say, “Five, and their sixth being their dog,” guessing at the unknown. And they will say, “Seven, and their eighth being their dog.” Say, “My Lord knows best their number.” None knows them except a few. So do not argue concerning them except with an obvious argument, and do not consult any of them about them.

18:26Say, “God knows best how long they stayed.” His is the mystery of the heavens and the earth. By Him you see and hear. They have no guardian apart from Him, and He shares His Sovereignty with no one.

18:32And cite for them the parable of two men. To one of them We gave two gardens of vine, and We surrounded them with palms-trees, and We placed between them crops.

18:38But as for me, He is God, my Lord, and I never associate with my Lord anyone.

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.”

18:47On the Day when We set the mountains in motion; and you see the earth emerging; and We gather them together, and leave none of them behind.

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.

18:71So they set out. Until, when they had boarded the boat, he holed it. He said, “Did you hole it, to drown its passengers? You have done something awful.”

18:74Then they set out. Until, when they encountered a boy, he killed him. He said, “Did you kill a pure soul, who killed no one? You have done something terrible.”

18:81So we wanted their Lord to replace him with someone better in purity, and closer to mercy.

18:99On that Day, We will leave them surging upon one another. And the Trumpet will be blown, and We will gather them together.

18:110Say, “I am only a human being like you, being inspired that your god is One God. Whoever hopes to meet his Lord, let him work righteousness, and never associate anyone with the service of his Lord.”
