(15:17) And We have protected it from every devil expelled [from the mercy of Allah] (15:18) Except one who steals a hearing and is pursued by a clear burning flame. (15:19) And the earth - We have spread it and cast therein firmly set mountains and caused to grow therein [something] of every well-balanced thing. (15:20) And We have made for you therein means of living and [for] those for whom you are not providers.
