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

18:10When the youths took shelter in the cave, they said, “Our Lord, give us mercy from Yourself, and bless our affair with guidance.”

18:16“Now that you have withdrawn from them, and from what they worship besides God, take shelter in the cave.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.”

18:58Your 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.

18:65Then they came upon a servant of Ours, whom We had blessed with mercy from Us, and had taught him knowledge from Our Own.

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.

This is the interpretation of what you were unable to endure.”

18:98He said, “This is a mercy from my Lord. But when the promise of my Lord comes true, He will turn it into rubble, and the promise of my Lord is always true.”
