Is it essential for a woman to be constantly reminded of her sexuality? Why is she expected to be always conscious of it?
Whether a woman herself is always conscious of her sexuality or not, it is natural for a man (who sees her) to be conscious of it. Islam is a religion based on nature, i.e. human nature. It takes into account all the natural instincts of man and woman and does not negate them. Rather it provides guidelines as to how they are to be handled. Islamic laws reflect a realistic awareness of human nature. The principle that governs hijab is that ‘Prevention is better than cure’.
