An-Nur 24:30
قُل لِّلْمُؤْمِنِينَ يَغُضُّوا۟ مِنْ أَبْصَـٰرِهِمْ وَيَحْفَظُوا۟ فُرُوجَهُمْ ۚ ذَٰلِكَ أَزْكَىٰ لَهُمْ ۗ إِنَّ ٱللَّهَ خَبِيرٌۢ بِمَا يَصْنَعُونَ

"Tell the believing men to reduce [some] of their vision and guard their private parts. That is purer for them. Indeed, Allāh is [fully] Aware of what they do."
An-Nur 24:30, translation by Sahih International
A short reflection
Tell the believing men to lower their gaze and guard their private parts. That is purer for them.
