A few prominent Alid supporters in Kufa felt guilty for abandoning Husayn after having invited him to revolt. To atone for what they perceived as their sin, they began a movement known as the Tawwabin, under Sulayman ibn Surad, a companion of Muhammad, to fight the Umayyads. As long as Iraq was in Umayyad hands, the movement remained underground. After the death of Yazid in November 683, the people of Iraq drove out the Umayyad governor Ibn Ziyad; The Tawwabin called on the people to avenge Husayn's death, attracting large-scale support. Lacking any political program, they intended to punish the Umayyads or sacrifice themselves in the struggle. Their slogan was "Revenge for Husayn". Mukhtar al-Thaqafi, another prominent pro-Alid of Kufa, attempted to dissuade the Tawwabin from this endeavor in favor of an organized movement to take control of the city, but Ibn Surad's stature as a companion of Muhammad and an old ally of Ali, prevented most of his followers from accepting Mukhtar's proposal. Although 16,000 men enlisted to fight, only 4,000 mustered. In November 684, the Tawwabin left to confront the Umayyads, after mourning for a day at Husayn's grave in Karbala. The armies met in January 685 at the three-day Battle of Ayn al-Warda in present-day northern Syria; most of the Tawwabin, including Ibn Surad, were killed. A few escaped to Kufa and joined Mukhtar.
