Q. Is cap mandatory in Islam?

Answer

Yes, it is believed that not wearing a head covering when praying is contrary to the Prophet's teachings. Shaykh Muhammad Hisham Kabbani, in his Encyclopaedia of Islamic Doctrine, said that women should always cover their heads in prayer since it is part of the quality of adornment that Allah ordained. The chechia is a traditional head covering for males in Tunisia (handmade from wool). Pakol hats are widely worn in Afghanistan. The hats are commonly referred to as kufis in the United States and the United Kingdom. African Muslims commonly wear the karakul hat. Among Malays, taqiyah is most commonly called kopiah. Muslims in Russia typically cover their heads with a doppa (rug cap).
