Alaa innahum yasnoona sudoorahum liyastakhfoo minh; alaa heena yastaghshoona siyaabahum ya'lamu maa yusiroona wa maa yu'linoon; innahoo 'aleemum bizaatis sudoor
Unquestionably, they [i.e., the disbelievers] turn away their breasts to hide themselves from him. Unquestionably, [even] when they cover themselves in their clothing, He [i.e., Allah] knows what they conceal and what they declare. Indeed, He is Knowing of that within the breasts.
1 Mufti Taqi Usmani
Beware, they bend their chests to hide from Him. Beware, when they cover up themselves with their clothes, He knows what they hide and what they expose. Surely, He is All Aware of what lies in the hearts.
