The purpose why Islam propound Muslim women to wear hijab is because this long fabric covers her body modestly that doesn’t reveal her figure. It is said to wear outer garment to hid their structure and leaving hands & face are permitted to males who are not close to her. Wearing hijab not just alter one’s appearance also the way she speak, walk and conduct with others in the society.
Muslim men and women adhere to almighty’s saying and obey without interrogating since He knows what is good for His creations.
Islam encourages women empowerment through hijab, that emphasis her spiritual beauty instead transfixing up on her physical appearance. Without losing their modesty women will be an active participant in contributing the society. Islam never impose suppression or oppression over women via hijab, it is the first self-defence to a women against anti-social elements.
