The Hijrah (هِجْرَة‎‎) is the migration or journey of the Islamic prophet Muhammed and his followers from Mecca to Yathrib, later renamed by him to Medina, in the year 622. After being warned of a plot to assassinate him, Muhammed secretly left his home in Mecca to emigrate to Yathrib, 320 km north of Mecca, with his companion Abu Bakr. Yathrib was soon renamed Madinat an-Nabi (مَـديـنـة الـنّـبي‎‎, literally "City of the Prophet"), but an-Nabi was soon dropped, so its name is "Medina", meaning "the city".
