Martial Arts for ladies
Q: If there are ladies only Martial Arts actives are you allowed to remove your headscarf, if it is woman only? However there are non-Muslims in the room? Is it best to remain modest at all times. Is there any rules on this?
A: The texts say that a Muslim woman must cover her nakedness (this includes the head) in front of disbelieving women and even in front of immoral Muslim women.
The reason given is that they may describe the woman’s private appearance to others. Therefore, if a woman feels safe that this won’t happen, it is okay for her to uncover.
