(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.
