In Islam, the term awrah refers to the intimate parts of the human body that must be covered by clothing. The awrah of a woman in front of her mahrams, such as her father, brother, and nephew, is her entire body except for that which usually appears, such as the face and hair, neck, forearms, and feet. The awrah of a woman with another woman is the area between the navel and the knee, whether the woman is her mother, sister, or not her mahram. The schools of Islamic law differ concerning the parts of the body a woman must cover in the presence of her maharim and Muslim women. The Hanafis and the Shafi’is say that it is wajib for her to cover the area between the navel and the knees in their presence. The Imamiyyah observe that it is wajib to cover one’s awrah in front of a child of discriminating age, who can describe what he sees, though it is not wajib before the one who is incapable of doing so.
It is worth noting that the term awrah is also used in other contexts in the Quran. For example, in Surah Al-Ahzab, it concerns fleeing from battle, and it means "vulnerable". In the story of the creation of Adam and Eve in the Garden, the term saw’ah is used as an equivalent to awrah. Certain scholars have concluded from the above differences that a womans voice is also her awrah in some cases.
In summary, awrah in Islam refers to the intimate parts of the human body that must be covered by clothing. The specific parts that must be covered depend on the context and the people present.
