Ridda Wars

The Ridda wars (Arabic: حروب الردة), also known as the Wars of Apostasy, were a series of military campaigns launched by the Caliph Abu Bakr against rebel Arabian tribes during 632 and 633 AD, just after Muhammad died. The rebels' position was that they had submitted to Muhammad as the prophet of God, but owed nothing to Abu Bakr. Some rebels followed either Tulayha or Musaylima or Sajjah, all of whom claimed prophethood. Most of the tribes were defeated and brought back to Islam. The peoples surrounding Mecca did not revolt.
