In the Name of God, the Merciful, the Compassionate.
So glorify God when you reach evening and when you rise in the morning; for all praise is His in the heavens and on earth, and towards the end of the day and when you have reached noon.1
Brother! You ask me concerning the wisdom in the specified times of the five daily prayers. I shall point out only one of the many instances of wisdom in the times.
Yes, like each of the times of prayer marks the start of an important revolution, so also is each a mirror to Divine disposal of power and to the universal Divine bounties within that disposal. Thus, more glorification and extolling of the Ail-Powerful One of Glory have been ordered at those times, and more praise and thanks for all the innumerable bounties accumulated between each of the times, which is the meaning of the prescribed prayers. In order to understand a little this subtle and profound meaning, you should listen together with my own soul to the following five 'Points'.
The meaning of the prayers is the offering of glorification, praise, and thanks to Almighty God. That is to say, uttering Glory be to God by word and action before God's glory and sublimity, it is to hallow and worship Him. And declaring God is Most Great through word and act before His sheer perfection, it is to exalt and magnify Him. And saying All praise be to God with the heart, tongue, and body, it is to offer thanks before His utter beauty. That is to say, glorification, exaltation, and praise are like the seeds of the prayers. That is why these three things are present in every part of the prayers, in all the actions and words. It is also why these blessed words are each repeated thirty-three times after the prayers, in order to strengthen and reiterate the prayers' meaning. The meaning of the prayers is confirmed through these concise summaries.
