Causes of Differences Between Imam Husain and Yazid
The Ahli-Bayt (members of the Holy Nabi’s family) had a valid claim to Khulafat for themselves. Soon after the death of Mu’awiyah bin Abu Sufyan, his son Yazid declared himself the Khalif since he had been nominated a successor to Mu’awiyah during his lifetime. Yazid demanded allegiance from Hazrat Husain ibn ‘Ali (Radiyallahu ‘anh). As the nomination to Caliphate was contrary to the spirit of the Islamic constitution, Hazrat Husain ibn ‘Ali (Radiyallahu ‘anh) was averse to it and he, therefore, refused to take the oath of allegiance in favor of Yazid.
Khalif Hazrat ‘Ali (Radiyallahu ‘anh) declared Kufa as the Capital of Caliphate. Consequently a large number of supporters of Ahli-Bayt were gathered there. They invited Hazrat Husain (Radiyallahu ‘anh) to Kufa and assured their support to him. Hazrat Imam Husain (Radiyallahu ‘anh) deputed his cousin Hazrat Muslim bin ‘Aqil (Radiyallahu ‘anh) for obtaining bay’ah (allegiance) from the residents of Kufa and himself started preparation for undertaking a journey to Kufa.
