The purpose of Salat is to remember God

[20:14] “I am GOD; there is no other god beside Me. You shall worship Me alone, and observe the Contact Prayers (Salat) to remember Me.

إِنَّنِي أَنَا اللَّهُ لَا إِلَٰهَ إِلَّا أَنَا فَاعْبُدْنِي وَأَقِمِ الصَّلَاةَ لِذِكْرِي

[62:10] Once the Contact Prayer (Salat) is completed, you may spread through the land to seek GOD’s bounties, and continue to remember GOD frequently, that you may succeed.

فَإِذَا قُضِيَتِ الصَّلَاةُ فَانْتَشِرُوا فِي الْأَرْضِ وَابْتَغُوا مِنْ فَضْلِ اللَّهِ وَاذْكُرُوا اللَّهَ كَثِيرًا لَعَلَّكُمْ تُفْلِحُونَ

Additionally, the Salat confirms that we worship God alone and are committed to the path of righteousness. Therefore, evil and vice are prohibited through the Salat.

[29:45] You shall recite what is revealed to you of the scripture, and observe the Contact Prayers (Salat), for the Contact Prayers prohibit evil and vice. But the remembrance of GOD (through Salat) is the most important objective. GOD knows everything you do.

اتْلُ مَا أُوحِيَ إِلَيْكَ مِنَ الْكِتَابِ وَأَقِمِ الصَّلَاةَ إِنَّ الصَّلَاةَ تَنْهَىٰ عَنِ الْفَحْشَاءِ وَالْمُنْكَرِ وَلَذِكْرُ اللَّهِ أَكْبَرُ وَاللَّهُ يَعْلَمُ مَا تَصْنَعُونَ
