The Battle of Al-Yamamah took place in 632 CE during the early Islamic conquests. It was fought between the forces of the newly unified Islamic state, led by the companion of the Prophet Muhammad, Abu Bakr, and the rebel tribes of the Arabian Peninsula, particularly the followers of the false prophet Musaylimah. This battle was significant in consolidating Islamic authority after the death of Muhammad. The battle occurred near the town of Al-Yamamah, in present-day Saudi Arabia. It was marked by fierce fighting and high casualties on both sides. Ultimately, the Islamic forces emerged victorious, leading to the defeat of Musaylimah and the end of his claim to prophethood, which helped to unify the Arabian tribes under Islam.
