﴿ ٱتْلُ مَآ أُوحِىَ إِلَيْكَ مِنَ ٱلْكِتَٰبِ وَأَقِمِ ٱلصَّلَوٰةَ ۖ إِنَّ ٱلصَّلَوٰةَ تَنْهَىٰ عَنِ ٱلْفَحْشَآءِ وَٱلْمُنكَرِ ۗ وَلَذِكْرُ ٱللَّهِ أَكْبَرُ ۗ وَٱللَّهُ يَعْلَمُ مَا تَصْنَعُونَ ﴾

“CONVEY [unto others] whatever of this divine writ has been revealed unto thee, and be constant in prayer: for, behold, prayer restrains [man] from loathsome deeds and from all that runs counter to reason; and remembrance of God is indeed the greatest [good]. And God knows all that you do.”

Recite what has been revealed to you of the Book the Qur’ān and maintain prayer; truly prayer prohibits lewd acts and indecency defined as such according to the Law. In other words that is its purpose provided that the person adheres to observance of it. And the remembrance of God is surely greater than other acts of obedience and God knows what you do and He will requite you for them.
