The early forms of Muslim culture were predominantly Arab. With the rapid expansion of the Islamic empires, Muslim culture has influenced and assimilated much from the Persian, Caucasian, Bangladeshi, Turkic, Mongol, Indian, Malay, Somali, Berber, Egyptian, Indonesian, and Moro cultures.Islamic culture generally includes all the practices which have developed around the religion of Islam, including Qur'anic ones such as prayer (salat) and non-Qur'anic such as divisions of the world in Islam. It includes the Baul tradition of Bengal. There are variations in the application of Islamic beliefs in different cultures and traditions.
