Kur’an 24:30 — sura An-Nur, 30. ajet

قُل لِّلۡمُؤۡمِنِينَ يَغُضُّواْ مِنۡ أَبۡصَٰرِهِمۡ وَيَحۡفَظُواْ فُرُوجَهُمۡۚ ذَٰلِكَ أَزۡكَىٰ لَهُمۡۚ إِنَّ ٱللَّهَ خَبِيرُۢ بِمَا يَصۡنَعُونَ

Reci vjernicima neka obore poglede svoje i neka vode brigu o stidnim mjestima svojim; to im je bolje, jer Allah, uistinu, zna ono što oni rade.

Tell the believing men to reduce [some] of their vision and guard their private parts. That is purer for them. Indeed, Allah is Acquainted with what they do
