Qur'an 24:30 · An-Noor

قُل لِّلْمُؤْمِنِينَ يَغُضُّوا۟ مِنْ أَبْصَٰرِهِمْ وَيَحْفَظُوا۟ فُرُوجَهُمْ ۚ ذَٰلِكَ أَزْكَىٰ لَهُمْ ۗ إِنَّ ٱللَّهَ خَبِيرٌۢ بِمَا يَصْنَعُونَ

(30) Tell the believing men to reduce [some] of their vision[988] and guard their private parts.[989] That is purer for them. Indeed, Allāh is [fully] Aware of what they do.
