Sajah

Sajah bint Al-Harith ibn Suayd (, fl. 630s CE) from the tribe of Banu Taghlib, was an Arab Christian and one of a series of people (including her future husband Musaylimah) who claimed to be a prophet in 7th-century Arabia. She was the only female claiming to be a prophetess during the Wars of Apostasy in Early Islamic Period. Her father, Al-Harith, belonged to the Banu Taghlib tribe of Iraq.
History.
During the Wars of Apostasy which emerged following the death of Muhammad, Sajah declared she was a prophetess after learning 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 joined her against Medina. However, her planned attack on Medina was called off after she learned that the army of Khalid ibn al-Walid had defeated 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 converted to Islam.
