Definition of Hijaab and its legal ruling according to the Law of Allah

Have you wondered what the word ‘HIJAAB’ mean (a word that has been in the spotlight of the media of the west, especially in the last decade)? Below is the definition of Hijaab, both the dictionary meaning and the Shar’i meaning. 

 Definition of 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). If you ever asked yourself that is Hijaab, Fardh/ compulsory upon a Muslim woman or is it an optional thing? Well, the answer is ‘YES, it is Fardh. 
Definition of Fardh: The command of a fardh is communicated by a definite text wherein there is no ambiguity, clear and specific. As a consequence the obligation emanating from a fard is of a greater degree than that from a Wajib. The omission of a fard invalidates the act. To act upon it and to believe in it is binding. One who refuses to believe in a Fard such as Falah or Zakah is rendered an unbeliever. This saying of Allah in the Holy Quran makes the act of wearing Hijaab for Muslim women Fardh: "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." A Muslim woman fells the obligation and then fulfills it with her own choice to please Allah.
