Or that he should be negligent and consider as unimportant a duty that is on the one hand simple and evident and on the other significant to such a degree? How could he concern himself with the most natural and common acts such as eating, drinking and sleeping and give hundreds of commands concerning them, yet remain completely silent about this important problem and not appoint someone in his own place?
Even if we accepted the hypothesis (which Shi'ism does not accept) that the appointment of the ruler of Islamic society is given by the Shari'ah to the people themselves, still it would be necessary for the Prophet to give an explanation concerning this matter. He would have had to give the necessary instructions to the community so that they would be aware of the problem upon which the existence and growth of Islamic society and the life of religious symbols and observances depended and relied.
Yet there is no trace of such a prophetic explanation or religious instruction. If there had been such a thing, those who succeeded the Prophet and held the reins of power in their hands would not have opposed it. Actually, the first caliph transferred the caliphate to the second caliph by bequest. The second caliph chose the third caliph through a six-man council of which he was himself determined and ordered. Mu'awiyah forced Imam Hasan to make peace and in this way carried away the caliphate.
After this even the caliphate was converted into a hereditary monarchy. Gradually many religious observances identified with the early years of Islamic rule (such as holy war, commanding what is lawful and prohibiting what is forbidden, the establishment of boundaries for human action) were weakened or even disappeared from the political life of the community, nullifying in this domain the efforts of the Prophet of Islam.
Shi'ism has studied and investigated the primordial nature of man and the continuous tradition of wisdom that has survived among men.
It has penetrated into the principal purpose of Islam which is to revivify man's primordial nature, and has investigated such things as the methods used by the Prophet in guiding the community ; the troubles which entangled Islam and the Muslims and which led to division and separation ; and the short life of the Muslim governments of the early centuries, which were characterized by negligence and lack of strict religious principles.
