Quran 11:5 from Surah Hud on Divine Marvels.
أَلَآ إِنَّهُمۡ يَثۡنُونَ صُدُورَهُمۡ لِيَسۡتَخۡفُواْ مِنۡهُۚ أَلَا حِينَ يَسۡتَغۡشُونَ ثِيَابَهُمۡ يَعۡلَمُ مَا يُسِرُّونَ وَمَا يُعۡلِنُونَۚ إِنَّهُۥ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ
English translation: No doubt! They fold up their breasts that they may hide from Him Surely when they cover (themselves) (with) their garments He knows what they conceal and what they reveal Indeed He (is) All-Knower of what (is in) the breasts
Transliteration: ala innahum yathnuna sudurahum liyastakhfu min'hu ala hina yastaghshuna thiyabahum ya'lamu ma yusirruna wama yu'linuna innahu alimun bidhati al-suduri
