 Many Arab Historians claim that the pre- and post-Islamic Arabs of the Arabian Peninsula region such as the Quraish, Ansar, Qahtanites, Kindites, Nabateans, Qedarites, Adnanites, Himyarites, Lakhmids, Ghassanids, Arabian Jews and others used to wear the turban, as opposed to the Keffiyeh which is popular today in the Arabian peninsula.The Arabian Hejazi turban is worn today by some Ulama and Imams.In most countries of the Arabian peninsula, a plain or checkered scarf (called "keffiyeh", "ghutrah", "shumagh" or "chefiyah"), described as a turban is often worn, though the Arabian turban tradition remains strong in Oman (see Sultan Qaboos of Oman), Sudan and some parts of the Arabian peninsula.
