67:3He who created seven heavens in layers. You see no discrepancy in the creation of the Compassionate. Look again. Can you see any cracks?

67:4Then look again, and again, and your sight will return to you dazzled and exhausted.

67:5We have adorned the lower heaven with lanterns, and made them missiles against the devils; and We have prepared for them the punishment of the Blaze.

67:17Or are you confident that the One in Heaven will not unleash against you a violent storm? Then you will know what My warning is like.

67:20Or who is this who is a force for you to protect you against the Compassionate? The disbelievers are in nothing but delusion.
