Sajah bint al-Harith ibn Suaeed from tribe of Banu Tamim [1] she was Arab Christian protected first by her tribe then cause a split within Banu Tamim and finally defended by Banu Hanifa.[2] Her father, Al-Haris, belonged to the Bani Yarbu section of the Bani Tamim tribe. Her mother belonged to the Banu Taghlib tribe of Iraq.
During the apostasy movement after the death of Muhammad, Sajah declared she was a prophetess[3] when she learned that Musaylimah and Tulayha had declared prophethood. Before claiming to be a prophetess, Sajah had a reputation as a soothsayer. Thereafter, 4,000 people gathered around her to march on Medina. Others were forced to join her (against their wills) against Medina. However, her planned attack on Medina was called off after she learnt of Khalid ibn al-Walid’s army defeating Tulayha al-Asadi (another self-proclaimed prophet). Thereafter, she sought cooperation with Musaylimah to oppose the threat of Khalid. A mutual understanding was initially reached with Musaylimah. However, Sajah later married Musaylimah and accepted his self-declared prophethood. Khalid then crushed the remaining rebellious elements around Sajah, and then moved on to crush Musaylimah. After the Battle of Yamama where Musaylimah was killed, Sajah returned to Islam.
