(15:12) Thus do We insert denial into the hearts of the criminals. (15:13) They will not believe in it, while there has already occurred the precedent of the former peoples. (15:14) And [even] if We opened to them a gate from the heaven and they continued therein to ascend, (15:15) They would say, "Our eyes have only been dazzled. Rather, we are a people affected by magic." (15:16) And We have placed within the heaven great stars and have beautified it for the observers. (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. (15:21) And there is not a thing but that with Us are its depositories, and We do not send it down except according to a known measure.
