In the Islamic Shariah, adoption of the Hijab (Veil) for the women is mandatory and not recommendatory. There are seven verses in the Holy Quran concerning the Hijab.
Islam declares women as precious jewels and honors them with the wealth of virtue, decency, greatness and majesty.
To protect her honor and chastity, Hijab has been ordered and she is ordered to Hijab herself, so that this precious jewel is not blemished with ill-sight.
Alas! Instead of appreciating this precious gift of Islam, Some materialistic people and others who have nefarious aims oppose this. In the present situation, it has become a very serious issue.
