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?”

18:39When you entered your garden, why did you not say, “As God wills; there is no power except through God”? Although you see me inferior to you in wealth and children.
