Surah Hud (Hud), Verse 5

اَلَاۤ اِنَّهُمْ یَثْنُوْنَ صُدُوْرَهُمْ لِیَسْتَخْفُوْا مِنْهُ اَلَا حِیْنَ یَسْتَغْشُوْنَ ثِیَابَهُمْ یَعْلَمُ مَا یُسِرُّوْنَ وَمَا یُعْلِنُوْنَ اِنَّهٗ عَلِیْمٌۢ بِذَاتِ الصُّدُوْرِ ۟

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.”
