Do you have an explanation to prompt your vision and amazement, on the matter from your Lord how He informs and extends the darkness and smoke? And if He wanted, He could have made it fixed and constant. So, we made the sun its proof over the existence of the shadow. Then if not for the sun the dark or the smoke could not be acknowledged.
We as human beings must learn to observe the creation and the authority of G-d and consider how we are to live our lives in submission and obedience to Him. The light of intelligent living must overcome the darkness of ignorance and doubt.
