أَلَآ إِنَّهُمۡ يَثۡنُونَ صُدُورَهُمۡ لِيَسۡتَخۡفُواْ مِنۡهُۚ أَلَا حِينَ يَسۡتَغۡشُونَ ثِيَابَهُمۡ يَعۡلَمُ مَا يُسِرُّونَ وَمَا يُعۡلِنُونَۚ إِنَّهُۥ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ

Alaa innahum yasnoona sudoorahum liyastakhfoo minh; alaa heena yastaghshoona siyaabahum ya'lamu maa yusirroona wa maa yu'linoon; innahoo 'aleemun bizaatis sudoor

Behold! they fold up their hearts, that they may lie hid from Him! Ah! even when they cover themselves with their garments, He knoweth what they conceal, and what they reveal: for He knoweth well the (inmost secrets) of the hearts.

— Hud (هُود), 11:5
