Muslim ibn Aqil (632–680)
Born 632 CE, died 680 CE.
Muslim ibn Aqil (Arabic: مُسْلِم ٱبْن عَقِيل ٱلْهَاشِمِيّ, romanized: Muslim ibn ʿAqīl al-Hāshimī) was the son of Aqil ibn Abi Talib, a paternal cousin of the Islamic prophet Muhammad and a brother of Ali. Muslim was therefore a nephew of Ali as well as a close relative of Husayn. Husayn dispatched him to Kufa to ascertain their support upon the accession of the Umayyad caliph Yazid. The Kufans welcomed Muslim and overwhelmingly pledged to support Husayn against the Umayyad rule, which they considered illegitimate and tyrannical. In response, Yazid replaced the mild governor of the city with his strongman Ubayd-Allah ibn Ziyad, who soon discovered the hideout of Muslim through an informant. When Ibn Ziyad imprisoned and killed Hani ibn Urwa, who was secretly sheltering Muslim, he came out in open revolt and surrounded the governor's palace with his supporters in September 680 CE. With a combination of threats and promises, however, Ibn Ziyad induced Kufan tribal leaders to abandon Muslim and withdraw their men. A deserted Muslim was arrested after a strong resistance and executed. Before this turn of events, he had written to Husayn and urged him to come to Kufa.
