The Taqiyah (Arabic: طاقية, ALA-LC: ṭāqīyah) or araqchin (Persian: عرقچین) is a short, rounded skullcap. It is often worn for religious purposes; for example, Muslims believe that the Islamic prophet Muhammad used to keep his head covered, therefore making it mustahabb (i.e., it is commendable to cover the head in order to emulate him). Muslim men often wear them during the five daily prayers. The topi cap is often worn with shalwar kameez, which is the national costume of Pakistan.
