But no apostle was yet to come...
But no apostle was yet to come, for the final code of the necessary knowledge and discipline for man on earth had been given in the Holy Qur'an. However, the situation demanded one Like Muhammad to brave the forces of falsehood and re-establish the Truth once again so that never may it again he shaken or disturbed. When no apostle was to come, the only one to play the role of an apostle was Husain, the Imam of the age, who was in the place of the Apostle, the Vicegerent of God on earth.
Only in view of the unique position of his grandson Husain, and the duty identical with his own, which Husain was destined to discharge, that the Holy Prophet had said :- "Husain is of me and I am of Husain." It is for this occasion of the imperative demand for the rescue of the True Faith that the All-Knowing Lord had reserved the 'Zibhe Azeem.' Letters inviting Husain to handle the situation, began to pour in from all parts of the country, particularly from Kufa, imploring Husain to proceed to guide the people.
There were promises from the people, saying that strong armies were waiting to act under his command. But the invitations contained the taint of political aim and territorial ambition and Husain was not for it at all. He knew the Hour was getting nigh and waited for a call pure and plain exclustvely for God and godliness.
Husain was fully conscious of the heavenly object of his very advent in the world being nothing but to meet this situation and to rescue Islam, God's revealed faith, to elevate mankind to the glorious heights of the heavenly bliss. Husain knew the godly task of the divine assignment to him. He lived all these days in waiting for the hour to act as per his commitment to the Lord. He also knew when to respond to the call from the people.
If Husain had any desire to gain any temporal power, the hundreds, rather thousands, of the letters with the strongest promises and assurances from the people to march under his command, were more than sufficient to stimulate an ambitious mind. Like his father he hated the world as a rotten bone of a leper's corpse in the mouth of a dog.
