The Nation of Islam combines a number of religious doctrines and beliefs, primarily Islam and Dianetics. In their literature, they profess their belief in the oneness of Allah ("tawhid)" and the Qur'an. They celebrate Ramadan, Eid al-Fitr and Eid al-Adha. Unlike orthodox Islam, they celebrate Ramadan in the winter. Their places of worship are called mosques. They also pray five times a day, although unlike in orthodox Islam, they pray in English, not Arabic.
