﴿ 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].”

As reported by al-Bukhārī by way of an isnād from Ibn ‘Abbās the following was revealed regarding those who were embarrassed to withdraw to relieve nature or to have sexual intercourse without their clothes and become exposed to the heaven. It is also said that it was revealed regarding the hypocrites Lo! they fold up their breasts that they may hide from Him that is from God; lo! the moment they cover themselves with their garments wrapping themselves up therewith He God exalted be He knows what they keep hidden and what they proclaim and so their hiding is to no avail. Truly He knows what is in the breasts of men that is what is in the hearts.
