who was the first one to migrate to madinah
Hegira The Hejira (Arabic: هِجْرَة‎) is the migration or journey of the Islamic prophet Muhammad and his followers from Mecca to Yathrib, later renamed by him to Medina, in the year 622.[1][6] In June 622, after being warned of a plot to assassinate him, Muhammad secretly left his home in Mecca to emigrate to Yathrib, 320 km (200 mi) north of Mecca, along with his companion Abu Bakr.[7] Yathrib was soon renamed Madīnat an-Nabī (Arabic: مَـديـنـة الـنّـبي‎, literally "City of the Prophet"), but an-Nabī was soon dropped, so its name is "Medina", meaning "the city".[8]
