Quran Hud 11:5
أَلَآ إِنَّهُمۡ يَثۡنُونَ صُدُورَهُمۡ لِيَسۡتَخۡفُواْ مِنۡهُۚ أَلَا حِينَ يَسۡتَغۡشُونَ ثِيَابَهُمۡ يَعۡلَمُ مَا يُسِرُّونَ وَمَا يُعۡلِنُونَۚ إِنَّهُۥ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ
Translation
Unquestionably, they [i.e., the disbelievers] turn away their breasts to hide themselves from him. Unquestionably, [even] when they cover themselves in their clothing, He [i.e., Allāh] knows what they conceal and what they declare. Indeed, He is Knowing of that within the breasts.
