Intimate parts in Islam

The intimate parts of the human body must, according to Islam, be covered by clothing. Exposing the intimate parts of the body is unlawful in Islam as the Quran instructs the covering of genitals, and for adult females the breasts. Exposing them is regarded as sin. Precisely which body parts must be covered varies between different schools of Islamic thought. The Quran admonishes Muslim women to dress modestly and cover their breasts and genitals. The Quran explicitly states that "O wives of the Prophet, you are not like anyone among women" (Quran 33: 32) and as such has separate rules specifically for the wives of the Prophet. Currently 'Awrah may be exposed for emergencies such as surgery. There is no reference where this is permitted.
