أَلَآ إِنَّهُمْ يَثْنُونَ صُدُورَهُمْ لِيَسْتَخْفُوا۟ مِنْهُ ۚ أَلَا حِينَ يَسْتَغْشُونَ ثِيَابَهُمْ يَعْلَمُ مَا يُسِرُّونَ وَمَا يُعْلِنُونَ ۚ إِنَّهُۥ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ
Lo! now they fold up their breasts that they may hide (their thoughts) from Him. At the very moment when they cover themselves with their clothing, Allah knoweth that which they keep hidden and that which they proclaim. Lo! He is Aware of what is in the breasts (of men).
