But in the light of this philosophy it is not necessary at all that the Holy Prophet should have designated Imam Ali on receiving a commandment from Allah, for only he and the Imams, inspired and endowed with Divine knowledge through the Holy Prophet, could receive such a Divine commandment, but that could not be the case subsequently.
Therefore if it is admitted that from the viewpoint of Islam the government is to be based on the principle of designation, it was not necessary for the Holy Prophet to nominate Imam Ali by revelation. He could appoint him at his personal discretion. The Imams also could use their discretion similarly. On this basis Imam Ali's designation to Khilafat was similar to the appointment of a Governor of Makkah or the appointment of an Amirul Hajj.
In such cases nobody says that the Holy Prophet on receiving revelation appointed such and such person the Governor of Makkah or, for example, sent Mu'az bin Jabal to Yemen for the propagation of Islam. In contrast everybody admits that the Holy Prophet was entrusted by Allah with the charge of the administration of people, and so he was authorized to act according to his own discretion in all matters in which he did not receive a revelation.
In the case of Imam Ali's designation to Khilafat also it may be said that this was the Holy Prophet's personal decision. If we advance the question of Imamat in such a simple way, it becomes a question of worldly government and ceases to be the question of Imamat that we are discussing. If this be the nature of the question, really there is no need that Divine revelation should intervene in it.
At the most Divine revelation can tell the Prophet that it is his duty to appoint as his successor whomsoever he deems fit, and that his successor also has to choose his successor in the same way. And so on till the Day of Resurrection.
If Imamat simply means government or rulership, then what the Sunnis say appears to be more attractive than what the Shi'ah say, for the Sunnis hold that a ruler has no right to choose the next ruler and that his successor should be chosen in a democratic way by the people, especially by those who have right to choose. But the question is not so simple.
On the whole the belief of the Shi'ah in the designation of Imam Ali and other Imams to Khilafat is an offshoot of another question which is more basic. Here an important question arises. The question is that the number of the Imams was not more than twelve.
