﴿ أَلَآ إِنَّهُمْ يَثْنُونَ صُدُورَهُمْ لِيَسْتَخْفُوا۟ مِنْهُ ۚ أَلَا حِينَ يَسْتَغْشُونَ ثِيَابَهُمْ يَعْلَمُ مَا يُسِرُّونَ وَمَا يُعْلِنُونَ ۚ إِنَّهُۥ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ ﴾

“Oh, verily, they [who are bent on denying the truth of this divine writ] are enshrouding their hearts in order to hide from Him. Oh, verily, [even] when they cover themselves with their garments [in order not to see or hear], He knows all that they keep secret as well as all that they bring into the open - for, behold, He has full knowledge of what is in the hearts [of men].”

(Lo! now they fold up their breasts that they may hide (their thoughts) from Him�) [11:5]. This verse was revealed about al-Akhnas ibn Shurayq who was good looking and sweet talking. When he met the Messenger of Allah, Allah bless him and give him peace, he pleased him but he always kept in his heart that which displeased him. Al-Kalbi said: �He used to sit with the Prophet, Allah bless him and give him peace, and display things that pleased the Prophet while hiding in his heart the opposite of what he displayed. And so Allah, exalted is He, revealed (Lo! now they fold up their breasts that they may hide (their thoughts)) their thoughts of enmity to Muhammad, Allah bless him and give him peace�.
