The Hijab in Islam is an act of obedience to Allah (God) and
to His Prophet and Messenger Muhammad (Peace Be Upon Him). He, Allah almighty, says:
"It is not for a believer, man or woman,when Allah
and His Messenger have decreed a matter that they should have an option in
their decision. And whoever disobeys Allah and His Messenger, has indeed
strayed in a plain error." (Qur'an 33:36)
Allah almighty also says:
"But no by your Lord, they can have no Faith,
until they make you, Muhammad (PBUH), a judge in all disputes between them, and
find in themselves no resistance against your decisions, and accept (them) with
full submission." (Qur'an 4:65)
Indeed, Allah ordered that women must put on the Hijab and
he says:
"And tell the believing women to lower their gaze
(from looking at forbidden things) and protect their private parts (from illegal
sexual acts, etc.) and not to show off their adornment except what must
(ordinarily) appear thereof, that they should draw their veils over their Juyubihinna." (Qur'an 24:31).
Allah almighty considered the dazzling display of beauty an
act of ignorance:
"And stay in your houses and do not display yourselves
like that of the times of Jahiliyeeyah (ignorance). " (Qur'an 33:33)
He, Most Glorified, says:
"And when you ask the Prophet's wives for anything
you want, ask them from behind a screen." (Qur'an 33:53)
The above verse does not apply only to the Prophet's wives
but to all of the believing women. Carefully read the following saying of Allah
almighty:
"O Prophet! Tell your wives and your daughters and
the women of the believers to draw their cloaks (veils) over their bodies (when
outdoors). That is most convenient that they should be known and not
molested."(Qur'an 33:59)
The Prophet (PBUH) said:
"The woman (i.e. any woman) is A'wrah", that is
she must be covered.
