Hijaab

Hijaab literally means screen, curtain, partition and concealment. As a verb it means to conceal oneself from the view. In Islam the word means to completely hide one's self from the view of the ghair mahram, (Men with whom marriage is permissible) The normal and general rule of Hijaab is total seclusion and segregation between males and females. This way women are seen by their husband and men that are mahram (men with whom marriage is not permissible due to the woman being one of the man's mothers, daughters, sisters, paternal aunts, maternal aunts, brothers' daughters, sisters' daughters, wetnurses, fellow wetnursed females, mothers-in-law, wives of his sons, and certain types of step daughters).
Allah says in the Holy Quran, 
"Oh Prophet! Tell your wives and your daughters and the women of the believers to draw their cloaks (veil) all over their bodies (i.e. screen themselves completely except the eyes or one eye to see the way). That will be better, that they should be known (as free respectable women) so as not to be annoyed. And Allah is ever Oft-Forgiving, Most Merciful."
The ladies who wear the hijaab feel liberated from materialism and venerably respected, recognised and honoured. The Hijaab which is not too different from the 'Habit' worn by traditional nuns and also includes a veil is necessary upon every woman who is close to the age of puberty or has reached it.
