سورة النور

قُلْ لِلْمُؤْمِنِينَ يَغُضُّوا مِنْ أَبْصَارِهِمْ وَيَحْفَظُوا فُرُوجَهُمْ ۚ ذَٰلِكَ أَزْكَىٰ لَهُمْ ۗ إِنَّ اللَّهَ خَبِيرٌ بِمَا يَصْنَعُونَ ﴿٣٠﴾

Surah an-Nur

30. Tell the believing men to restrain their looks, and to guard their privates. That is purer for them. Allah is Aware of what they do.
