The month of Muharram is the first month of the Islamic calendar year. An important and tragic event took place on the tenth of Muharram that shook the Muslim world. It was the murder of Imam Husain (A.S.), his family members, and his close friends by the army of Yazid. Yazid was at that time the despotic ruler of the Muslim world, who came to power as the self-proclaimed “sixth caliph of Islam” after the death of his father, Mu’awiya. Yazid gave himself the title of ameer-ul-mu’mineen, meaning “commander of the faithful.” 
Husain was one of the two grandsons of the Prophet Muhammad (S.A.A.W.), and the younger of the two sons of Hazrat Fatima (A.S.), the daughter of the Holy Prophet. The Holy Prophet loved his two grandsons, Hasan and Husain, dearly, and he used to call them his “sons,”.
