Ar-Rum 30:18

<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. This is when the night comes with its darkness, then in the morning the day comes with its light.

Then Allah says:</p><div class="arabic uthmani">وَعَشِيّاً وَحِينَ تُظْهِرُونَ</div><p>(and in `Ashiyya and when Tuzhirun.) -- the `Ashiyy is the time when the darkness is most intense, and Izhar is the brightest point of the day.

Yea, to Him be praise, in the heavens and on earth; and in the late afternoon and when the day begins to decline.

And His is all the praises and thanks in the heavens and the earth, and (glorify Him) in the afternoon (i.e. offer 'Asr prayer) and when you come up to the time, when the day begins to decline (i.e. offer Zuhr prayer). (Ibn 'Abbas said: "These are the five compulsory congregational prayers mentioned in the Quran)."

His is the praise in the heavens and on earth, and in the evening, and when you reach midday.
