Since the desire for women is something which men cannot resist easily, God has imposed strict regulations in His successive divine messages to make sure that such a desire will play its legitimate role in the human life and will not be got out of the lawful context in which it was essentially placed, given the fact that the satisfaction of such a desire outside its legitimate framework has considerable disadvantages and enormous damage threatening man’s happiness as they ruin his life and lose him the Hereafter.
One of such strict regulations is the imposition of hijab on women. That is to say, women are commanded to conceal their attractive parts whose charm cannot be resisted by men and only allowed to expose such outer parts of the body which do not cause much temptation and have such humanly reasonable adornment which is quite far away from such finery which involves deliberate display of woman’s beauty and intentional arousal of men’s desires.
In this sense, hijab was made incumbent in all divine messages, including Judaism, Christianity and Islam. No wonder, the female believers in any of the divine messages used to wear hijab.
