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

18:15“These people, our people, have taken to themselves gods other than Him. Why do they not bring a clear proof concerning them? Who, then, does greater wrong than he who invents lies and attributes them to God?”

18:21So it was, that We caused them to be discovered, that they would know that the promise of God is true, and that of the Hour there is no doubt. As they were disputing their case among themselves, they said, “Build over them a building.” Their Lord knows best about them. Those who prevailed over their case said, “We will set up over them a place of worship.”
