As a majority of indian muslim woman, i'm wearing a nose pins(piercing).
Some days ago, i had a doubt on piercing in islam... if it's allowed to wear nose pins ?!
I found something about this matter :
It is not permissible to pierce the belly button, or other body parts such as the lips, tongue, eyebrows etc.; this is not considered an adornment for the Muslim female in Islam. Only the ears and the nose are permissible to pierce and one can find examples of this taking place in the time of the Prophet and it was not forbidden.
To have other body parts pierced other than the ears and nose is mutilation (muthlah) of the human body which is forbidden in Islam. Both the person having it done and the doer will be in sin. Mutilation of this sort will indeed cause a great deal of harm to the body. It is highly possible that it could be a means of infection to cause irreversible harm to the body. This is not promoted in Islam but forbidden.
It is also an imitation of the non-Muslims (who invented this act and made it into a fashion) and has been highly popularized by actors and actresses as an object of beauty. In light of this it will be "tashabuh" (imitation) of a non-Muslim nation.
AN IMPORTANT ONE : women who have a nose piercing have to covert their face when they go outside !!!!
They have to wear the niqab !!!!
