Musaylimah al-Kadhdhāb

Musaylimah ibn Ḥabīb al-Ḥanafī (d. 12/633), commonly known in Islamic sources as Musaylimah al-Kadhdhāb (“Musaylimah the Liar”), was a prominent figure of Banū Ḥanīfah in al-Yamāmah whose claim to prophethood constituted one of the most significant challenges faced by the Muslim community during the final years of the Prophet Muḥammad and the period immediately following his death. As a leader among one of the most powerful tribes of central Arabia, Musaylimah exercised considerable political and religious influence in al-Yamāmah. His career occupies an important place in sīrah literature because it is directly connected to the Prophet’s interactions with Arabian tribes and to the broader process through which Islam was established throughout the Arabian Peninsula.

Musaylimah first appears in the historical record in connection with the delegation of Banū Ḥanīfah that visited Madinah during the “Year of Delegations” (ʿĀm al-Wufūd) in 9/630–31. According to the classical sīrah sources, he accompanied the delegation that met the Prophet and outwardly accepted Islam. Shortly thereafter, however, he began claiming a share in prophethood and sought recognition as a partner in Muḥammad’s mission. Islamic tradition preserves correspondence between the two, including Musaylimah’s letter asserting a joint prophetic authority and the Prophet’s reply rejecting his claim and affirming the universality and finality of the Islamic message. These exchanges made Musaylimah one of the most prominent opponents mentioned in the later chapters of the sīrah.

The challenge posed by Musaylimah was not merely theological but also political. Supported by substantial segments of Banū Ḥanīfah, he established a religious movement in al-Yamāmah that combined prophetic claims with tribal leadership. Classical Muslim historians record that he produced pronouncements and exhortations that he presented as revelations and attracted a considerable following among the inhabitants of central Arabia. His movement illustrates the complex interaction between tribal identity, regional autonomy, and religious authority during the final phase of the Prophet’s mission. Consequently, Musaylimah occupies an important place in discussions of the Prophet’s relations with Arabian tribes and the consolidation of the Islamic polity.

Following the Prophet’s death in 11/632, Musaylimah became the principal adversary of the Medinan state during the Ridda Wars. The first caliph, Abū Bakr, dispatched Muslim forces under Khālid ibn al-Walīd to suppress the rebellion. The ensuing Battle of al-Yamāmah, fought in 12/633, resulted in the defeat and death of Musaylimah and marked a decisive turning point in the unification of Arabia under Muslim rule. The battle also had lasting consequences for Islamic history, as the deaths of numerous Qurʾān reciters contributed to the initiative to collect and preserve the Qurʾānic text. For students of sīrah, Musaylimah is significant not only as a rival claimant to prophethood but also as a figure whose career illuminates the political, religious, and tribal challenges confronting the Muslim community at the end of the Prophetic era and the beginning of the caliphate.
