A niqāb or niqaab, also known as a ruband, is a long garment worn by some Muslim women in order to cover their entire body and face, excluding their eyes. It is an interpretation in Islam of the concept of hijab, and is worn in public and in all other places where a woman may encounter non-mahram men. Most prevalent in the Arabian Peninsula, the niqab is a controversial clothing item in many parts of the world, including in some Muslim-majority countries.

In modern usage, hijab generally refers to various head coverings conventionally worn by many Muslim women. It is similar to the tichel or snood worn by Orthodox Jewish women, certain headcoverings worn by some Christian women, such as the mantilla, apostolnik and wimple, and the dupatta worn by many Hindu and Sikh women. Whilst a hijab can come in many forms, it often specifically refers to a scarf wrapped around the head, covering the hair, neck and ears but leaving the face visible. The use of the hijab has been on the rise worldwide since the 1970s and is viewed by many Muslims as expressing modesty and faith; it has also been worn for purposes of adornment. There is a consensus among Islamic religious scholars that covering the head is either required or preferred, though some Muslim scholars and activists point out that it is not mandated.
