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. When it comes to the obligation for a Muslim woman to cover her hair and body, many have expressed confusion about the origin of this commandment. However, there has never been any debate within Sunni Islamic scholarship at any point in history regarding the obligation of hijab for all Muslim women who have reached the age of puberty.
