Is wearing hijab a choice?
To answer this question I must look to the named the Holy Qur’an, which Muslims claim to be the divine word of God.
The Qur’an states;
“And tell the believing women to reduce [some] of their vision and guard their private parts and not expose their adornment except that which [necessarily] appears thereof and to wrap [a portion of] their headcovers over their chests and not expose their adornment except to their husbands, their fathers, their husbands’ fathers, their sons, their husbands’ sons, their brothers, their brothers’ sons, their sisters’ sons, their women, that which their right hands possess, or those male attendants having no physical desire, or children who are not yet aware of the private aspects of women. And let them not stamp their feet to make known what they conceal of their adornment. And turn to Allah in repentance, all of you, O believers, that you might succeed.”
As you can see, Muslim women are commanded to cover their hair and not display their body to any male outside their family. If you anyone says a woman has a choice to wear hijab they are wrong. Although, there are lots of commandments that people don’t follow. You can still choose to follow a commandment.
The Prophet also said that when a girl reaches the age of menstruation it doesn't suit here that she shows parts of except her hands and face.
“Asma, daughter of AbuBakr, entered upon the Messenger of Allah (ﷺ) wearing thin clothes. The Messenger of Allah (ﷺ) turned his attention from her. He said: O Asma’, when a woman reaches the age of menstruation, it does not suit her that she displays her parts of body except this and this, and he pointed to his face and hands.”
