Which event resulted from the unexpected death of Muhammad

Muhammad’s continuing success gradually impinged on the Quraysh in Mecca. Some defected and joined his community. His marriage to a Quraysh woman provided him with a useful go-between. In 628 he and his followers tried to make an Islamized hajj but were forestalled by the Meccans. At Al-Ḥudaybiyah, outside Mecca, Muhammad granted a 10-year truce on the condition that the Meccans would allow a Muslim pilgrimage the next year. Even at this point, however, Muhammad’s control over his followers had its limits; his more zealous followers agreed to the pact only after much persuasion. As in all instances of charismatic leadership, persisting loyalty was correlated with continuing success. In the next year the Meccans allowed a Muslim hajj; and in the next, 630, the Muslims occupied Mecca without a struggle. Muhammad began to receive deputations from many parts of Arabia. By his death in 632 he was ruler of virtually all of it.
