Adopting the right ways to deal with events...
Adopting the right ways to deal with events, which will arise until Doomsday, based on the verses of the Holy Quran, or limited narrations related to us by the Prophet are huge problems indeed and beyond the conceivable power of ordinary people.
This is because the number of Quranic verses which deal with jurisprudential issues is not more than three hundred and the number of the narrations which are narrated from the Prophet concerning the issues of permitted and forbidden acts does not exceed four hundred.
Never can an ordinary man, with his limited knowledge, deal with the ever increasing events and occurrences of the present day Islamic community; rather, a capable man would be required to solve the problems with his Divine education. Such a learned man must be immune to all sorts of sins so that he could be trusted by all. Such a person should be appointed by God.
Another Interpretation Of The Issue Of The Perfection Of Religion Another interpretation of the issue of the perfection of religion that could be offered here is the continuity of the mission. This is because, according to numerous narrations, this verse was revealed to the Prophet on the day of Ghadir when Ali (as) was appointed by the Prophet as the Caliph Imam, his successor. Without an Imam there was no guarantee for the religion of Islam to continue with its existence.
The chances existed that Islam would cease to exist were it not for the Imams. Because of this, Ali (as) was appointed by the Prophet to continue the Prophet's mission. However, it should be noted that, after the Prophet’s demise divine revelation came to an end. This is because all of man’s needs, up to resurrection, were taken care of by the Prophet. But there are jurisprudential affairs which show themselves each day and should be resolved by the Prophet's successor.
Considering all this, we should admit that all of God's commands related to Islam were revealed to the Prophet during his lifetime. However, due to the limited years of prophethood and due to the daily problems he faced, he was unable to teach the Ummah all that he had received from Allah. Under such circumstances, the Prophet had to teach his successor, who like himself was innocent, all that he had received from God concerning the Divine commands and Islamic practical laws.
Naturally, such a knowledgeable person, who is innocent flaw less, could only be appointed by Allah. The Ummah could never appoint such a person.
