If Allah should aid you, no one can overcome you; but if He should forsake you, who is there that can aid you after Him? And upon Allah let the believers rely.
[ Quran 3-160]
O Prophet! Say to your wives and your daughters and the women of believers that they let down upon them their over-garments; this will be more proper, that they may be known, and thus they will not be given trouble. And Allah is Forgiving, Merciful.
-Al Quran 33:59
