It is said that Abu Hanifah made so much use of analogy because he was of Irani origin and the Iranians by nature tend to take much interest in mental exercises, and because he lived in Iraq which was far away from Medina, the centre of the traditionalists. Anyhow, he indulged too much in analogy. A Sunni writer says that one day Abu Hanifah went to a barber. His beard had a mixture of black and grey hair but the number of the grey hair was not very large.
He asked the barber to pull out the grey hair. The barber said: "If grey hair is pulled out, it tends to grow more copiously." Abu Hanifah said: "Then pull out the black hair, for my analogy says that in case grey hair grows copiously if it is pulled out, the same thing should happen in the case of black hair also." But the fact is that if there is any such rule, it applies to grey hair only, not to black hair. Anyhow, Abu Hanifah made similar deductions in the case of jurisprudence also.
Analogy from the Shi'ah Point of View When we refer to the Shi'ah traditions we find that according to them the need of analogy is felt only because of the wrong notion that the Qur'an and the Sunnah are not enough to provide all the necessary rules of law. The fact is that this notion is totally wrong.
We have received such a quantity of Prophetic traditions either directly or through the chosen descendants of the Holy Prophet, that if we refer to the principles laid down therein, we need not resort to analogical deduction at all. That is the spirit of Imamat from religious point of view. Islam is not merely a creed or a doctrine. It cannot be said that after its ideology has been enunciated by its founder it only requires a government to implement that ideology.
It is a complete code and that position of it must be kept in mind. No Question of Election in the Presence of an Infallible Imam From the viewpoint of leadership and rulership the position is that Imam Ali the Holy Prophet's successor who is as infallible as the Prophet himself and who has been designated by him to be his successor, cannot be placed at par with other people. His position is exceptional like that of the Prophet himself.
Therefore in his case there is no room for any election, consultation or any other such thing. In the case of the Prophet nobody ever said that he was only the Messenger of Allah and the people were at liberty to choose him or anybody else to be their ruler.
