Sikhism is the only religion in the world which requires its followers to tie a turban. The Sikh turban is thus an article of faith. People of many other cultures and religions wear turbans, but none are required to do so by their religion. Arabs wear turbans, people in the Indian dessert state of Rajasthan wear turbans, Africans wear turbans—but none of these people are ‘required’ to wear their turbans.
Sikh turbans may be of different colors, styles and types but are not hats. Sikhs tie their turbans anew each day. Asking a Sikh to take off his turban in say a fancy club or church is like asking a person to remove his pants. Sikh turbans become a part of a Sikh’s body and are usually removed only in the privacy of the house.
