Musaylima
Musaylima ibn Habib (died December 632 CE), commonly referred to as Musaylima al-Kadhdhab ("the Arch-Liar") in early Islamic historical accounts, was a seventh-century self-proclaimed prophet and tribal leader from the Banu Hanifa tribe in the Yamama region of central Arabia.[1][2] Contemporary with Muhammad, Musaylima sought an alliance or shared prophetic authority through correspondence, which was rebuffed by the Islamic prophet who addressed him dismissively as a liar.[3] Following Muhammad's death, Musaylima capitalized on regional instability to consolidate power, declaring sovereignty and attracting a substantial following among Arab tribes disaffected by Medinan centralization.[2] His movement posed one of the most serious threats during the Ridda Wars, culminating in a fierce confrontation with Caliph Abu Bakr's forces under Khalid ibn al-Walid at the Battle of Yamama, where Musaylima was killed by the Ethiopian warrior Wahshi ibn Harb amid heavy casualties on both sides.[2][3] This defeat effectively ended his bid for religious and political dominance, though remnants of his adherents persisted in isolated areas for centuries.[4]
