Edited sentence: Abu Bakr thus assumed power, ruling over the Rashidun Caliphate from 632 to 634 CE.Abu Bakr was present at the Farewell Pilgrimage, as well as the event of Ghadir Khumm, in 632 CE.After lengthy debates that included violence, Umar ibn Al-Khattab pledged allegiance to Abu Bakr at Saqifa; he was followed in this by two others at Saqifa, as well as a group of Bedouin tribesmen who had arrived at the scene.After the conclusion of the Ridda Wars, Abu Bakr launched campaigns into Syria and Persia, but died before their conclusion.Another significant event during Abu Bakr's reign was the seizure of the land of Fadak from Fatimah, Muhammad's daughter.He was succeeded by Umar.However, shortly after Muhammad died, Abu Bakr and some others left the still-unburied body of Muhammad and gathered at a place known as Saqifa.In 634 CE, Abu Bakr fell ill from a sickness and died shortly thereafter.Once in power, Abu Bakr launched the Ridda Wars to quell an outbreak of "apostasy" in various lands outside Medina.Saqifa was later described by the famous Sunni historian Al-Tabari as "a scene from the period of Jahiliya (the pre-Islamic era)".The Ridda Wars, however, were expanded to include the use of force against Muslims who did not recognize Abu Bakr's government, instead of solely focusing on those who had left Islam
