The Holy Prophet has said that in such circumstances if someone does not restrain such a caliph with his words and conduct from committing evil deeds it is necessary for Allah to send him to the same place to which He sends that oppressive caliph". It is the same thing to which the Holy Qur'an has alluded in these words: We have made some of the Imams {leaders} lead their followers to the Fire. (Surah al-Qasas, 28:41) All the leaders do not take their followers to Paradise.
Some of the Imams and leaders of the nation guide the people towards Paradise and good fortune, and that Paradise means in the general sense of progress, prosperity and greatness in this world as well as in the Hereafter. However, according to the Holy Qur'an and historical experience some Imams, like Yazid, drag their followers towards fire, torture and certain downfall. The Imam then explained more explicitly the conditions prevailing during those days in 60 A.H.
and said: "You should know that these people namely the agents of the Caliphate of Bani Umayya follow Satan, carry out his orders and do not forsake his obedience. In the same proportion they have disobeyed Allah and started committing crimes openly and have suspended the Divine punishments. They have appropriated the property of the Muslims to themselves i.e.
they have allocated to themselves the money which should have been credited to the public treasury of the Muslims; spent for their own selfish desires. They have treated the things made lawful by Allah to be unlawful and those made unlawful by Him to be lawful. Now that they have created these conditions, who can be more responsible to change them and eliminate the causes of the decline of the Muslims in accordance with the orders of the Holy Prophet than myself.
I am Husayn bin Ali, the son of Fatima, and one of those for whose sake the verse of Purification (33:33) and the verse of Mubahila (3:61) were revealed, and I am the disciple of Imam Ali, the Commander of the Faithful". Indeed, who could perform the task performed by Husayn bin Ali? Who could obtain friends like his friends and who could take his place in this movement? Ibn Abbas was a great scholar and commentator of the Holy Qur'an, a distinguished companion of the Holy Prophet and his cousin.
However, he could not perform the task performed by Husayn bin Ali. Muhammad bin Hanafiya was the brother of the Imam and son of Ali ibn Abi Talib but he was not equal to this occasion.
