Why girls cover in Islam?

Question

Why the Muslim girls cover?

Also why there are co different types of cover based on the country they are in. Like Hijab is so different than Barqa and there are also some with only a head scarf. In some countries they dont even cover most of their hair with an head scarf when in other countries they dont even show their eyes.

Why?

Answer 1

To protect their modesty. They type of cover chosen usually just depends on the girl herself. It is not compulsion to cover it is a choice. Allah looks favorably on the one who chooses to protect her modesty.  Most muslim women want to be covered as it is what they believe, like a christian woman wants to be seen carrying her bible.
