(Annoor) 24 : 30
قُلْ لِلْمُؤْمِنِينَ يَغُضُّوا مِنْ أَبْصَارِهِمْ وَيَحْفَظُوا فُرُوجَهُمْ ۚ ذَٰلِكَ أَزْكَىٰ لَهُمْ ۗ إِنَّ اللَّهَ خَبِيرٌ بِمَا يَصْنَعُونَ
You tell the believing men to lower their gaze and guard their private parts; that is purer for them, indeed Allah is acquainted with whatever they are producing.
The believer is the one who glorifies the Lord as: “Glory be to the One Who knows the treachery of the eyes and what is hidden into the chests” which testifies verse 40: 19. He is the one who has transformed his Jinn soulmate into a believer with Adhikr and keeps Lord in his heart as explained in verse 3: 102. So the believes Jinn soulmate will guard him from every shameful and forbidden thing. He follows the mode of prayer and lifestyle as explained in verses 7: 205-206. See explanation 7: 201 and 10: 61.
