Imam Hussain (PBUH)
Imam Hussain (PBUH) (Arabic: حسین ); sometimes spelled Hussein, was the son of Imam Ali (PBUH) (fourth Rashidun Caliph of Sunni , and first Imam of Shia Islam) and Lady Fatimah (PBUH) (daughter of the prophet Muhammad (PBUH) and the younger brother of Imam Hassan Mojtaba (PBUH). Imam Hussain (PBUH) is an important figure in Islam, as he is a member of the Ahl Al-Bayt (the household of Prophet Muhammad (PBUH) and Ahl al-Kisa) as well as being the third Shia Imam.
Imam Hussain (PBUH) is highly regarded by Muslims and many non-Muslims because he refused to pledge allegiance to Yazid the Umayyad caliph, because he considered the rule of the Umayyads unjust. As a consequence, he left Medina, his home town, and traveled to Mecca. There, the people of Kufa sent letters to him, asking his help. So he traveled toward Kufa. At Karbala his caravan was intercepted by Yazid’s army. He was killed and beheaded in the Battle of Karbala in 680 (61 AH) by Shimr Ibn Thil-Jawshan, along with most of his family and companions. The annual memorial for him, his family, his children and his companions is called Ashura (tenth day of the month Muharram) and is a day of mourning for Muslims and many non-Muslims.
The tragedy in Karbala has had an impact on religious conscience of Muslims beyond its sacredness among Shia. In the long term, the cruel killings at Karbala became an example of the brutality of the Umayyad and fueled the later Shia movements. Anger at Imam Hussain’s (PBUH) martyrdom was turned into a rallying cry that helped undermine and ultimately overthrow the Umayyad Caliphate.
