Is ear piercing permissible?

> Islam doesn't allow to change the features created by Allah like > removing the face hairs, creating a space between tooth artificially > to look beautiful.- Bhukhari I have some questions under this piercing topic: - Is it allowed to pierce ear for wearing jewellery? Is it considered as changing the feature created by Allah(subh)? - If ear piercing allowed, what is the rule for men and ear piercing? - Did any of the prophet's wives wear earrings?
