ভূমিকা
Shiavault - a Vault of Shia Islamic Books Imamate and Twelve Imams The Imamate and Succession Man through his God-given nature realizes without any doubt that no organized society, such as a country or city or village or tribe or even a household consisting of a few human beings, can continue to subsist without a leader and ruler who puts the wheel of the society in motion and whose will govern each individual's will and induces the members of that society to perform their social duty.
Without such a ruler the parts of this society become dispersed in a short time and disorder and confusion reign. Therefore, he who is the ruler and governor of a society, whether it be great or small, if he is interested in his own position and the continued existence of his society, will appoint a successor for himself if he is to be absent from his function temporarily or permanently. He will never abandon the domain of his rule and be oblivious to its existence or annihilation.
The head of a household who bids farewell to his house and household for a journey of a few days or months will appoint one of the members of the household or someone else as his successor and will leave the affairs of the house in his hands. The head of an institution, or the principle of a school, or the owner of a shop, if he is to be absent even for a few hours will select someone to represent him.
In the same way Islam is a religion which according to the text of the Holy Book and the Sunnah is established upon the basis of the primordial nature of things. It is a religion concerned with social life, as has been seen by every observer near and far. The special attention God and the Prophet have given to the social nature of this religion can never be denied or neglected. It is an incomparable feature of Islam.
The Holy Prophet was never oblivious to the problem of the formation of social groupings wherever the influence of Islam penetrated. Whenever a city or village fell into Muslim hands he would, in the shortest time possible, appoint a governor or ruler in whose hands he would leave the affairs of the Muslims. In very important military expeditions ordered for the Holy War (jihad), he would appoint more than one leader and commander, in order of succession.
In the war of Mu'tah he even appointed four leaders, so that if the first were to be killed the second would be recognized as the head and his command accepted and if the second were to be killed, then the third, and so on.
