Ar-Rum 30:17

<h2>The Command to pray Five Times Daily</h2><p>Here Allah glorifies Himself and commands His servants to glorify and praise Him at these times which come one after the other and are indicative of His might and power in the heavens.

So glorify God when you retire at night, and when you rise in the morning.
