Hussein ibn ‘Alī ibn Abī Ṭālib (Arabic: حسين بن علي بن أﺑﻲ طالب) (3rd Sha’aban 4 AH – 10thMuharram 61 AH; 8 January 626 CE – 10 October 680 CE, also spelled Hussayn) was the son of‘Alī ibn Abī Ṭālib and Fātimah Zahrā (daughter of theIslamic prophet Muhammad). Husayn is an important figure in Islam as he is a member of the Ahl al-Bayt (the household of Muhammad) and Ahl al-Kisa.
Husayn refused to pledge allegiance to Yazid I, the Umayyad caliph. He rose up to create a regime that would reinstate a “true” Islamic polity as opposed to what he considered the unjust rule of the Umayyads. As a consequence, Husayn was killed and beheaded in the Battle of Karbala in 680 (61AH) by Shimr Ibn Thil-Jawshan. The annual funeral in the memory of him, his family, his children and his As’haab (companions) is called Ashura (tenth day of Muharram).
