The Salat provides the nourishment needed by our souls and is a sure method of attaining righteousness and nearness to the all mighty.
The Quran lists several benefits attained from observing the Salat:
1- The Salat protects believers from evil and vice:
Observe the Salat, for the Salat forbids immorality and evil. 29:45
2- The Salat strengthens our belief and makes us attain certainty:
Glorify your Lord with praise, and be among the prostrators, and worship your Lord in order to attain certainty. 15:98-99
3- The Salat (along with charity) is the best investment for the Hereafter:
Those who recite God's Book, observe the Salat and give from what We have provided for them, secretly and publicly, are seeking a trade that can never go to waste: that He may pay them their reward in full and increase for them His favour. Indeed, He is Forgiving, Appreciative. 35:29-30
4- Above all, the Salat is to commemorate God:
Surely, the most important objective of the Salat is to commemorate God.
Recite what is revealed to you of the Book, and observe the Salat, for the Salat forbids immorality and evil, and the remembrance of God is of greater importance. God knows what you do. 29:45
I am God, there is no god except Me. Therefore, you shall worship Me and observe the Salat to commemorate Me. 20:14
