God almighty made the adherence to the Hijab a manifestation
for modesty and chastity:
"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)
In the above Verse there is an evidence that the recognition
of the apparent beauty of the woman is harmful to her. When the cause of
attraction ends, the restriction is removed. This is illustrated in the case of
elderly women who may have lost every aspect of attraction. Allah (God)
almighty made it permissible for them to lay aside their outer garments and
expose their faces and hands reminding, however, that it is still better for
them to keep their modesty:
"And as for women past child-bearing who do not
expect wed-lock, it is no sin for them if they discard their (outer) in such a
way as not to show their adornment; but it is best to be modest and Allah knows
and sees all things provided they do not make a display of their beauty; but it
is best to be modest and Allah knows and sees all things." (Qur'an 24:60)
So how about young women? Clearly they must stay modest find
not display their beauty.
