And We have appointed the night and the day as two Ayât (signs etc.). Then, We have obliterated the sign of the night (with darkness) while We have made the sign of the day illuminating, that you may seek bounty from your Lord, and that you may know the number of the years and the reckoning. And We have explained everything (in detail) with full explanation.
