Have you not seen how Allah extended the shadow from the rising of the Fajr to the rising of the sun? and had He willed He would have surely made it firm settled the sun not vanishing it, then We made the sun a sign it being deduced by its conditions upon its conditions, then the shadow was contracted a little a little, for whenever the elevation of the sun increased its reduction increased. And that is of the evidences on the power of Allah and His greatness, and that He alone is the One worthy of worship besides none other.
