text: First and foremost, because Almighty God (Allah) commands them to do so.   \nIn the Qur'an, Allah tells the believers to "lower their gaze and be modest."  \nSpecifically, it says:  "Say to the believing men that they should lower their gaze and guard their modesty; that will make for greater purity for them; and Allah is well acquainted with all that they do. And say to the believing women that they should lower their gaze and guard their modesty; and that they should not display their beauty and ornaments except what must ordinarily appear thereof; that they should draw their veils over their chests and not display their beauty except to their husbands, their fathers..."
