There are many matters in which we should not follow the verdict of a deceased mujtahid (from jihad, to strive, meaning in this case, one who strives to interpret and to formulate religious practice and law, as ijtihad refers to the process of striving) but should turn to the living mujtahid for guidance.
Many mujtahids were born later among you who were of higher rank in learning than those four "Imams." I do not know why preference is given to the latter so that none but they may be followed and the right of others ignored. In Shi’as jurisprudence, mujtahids in every age until the appearance of the Holy Imam of our time have the right to practice. In regard to new problems, we cannot follow the verdict of a deceased mujtahid.
Limitation to four schools of law has no basis It is strange that you call the Shi’as innovators and worshippers of the dead. They follow the injunctions of the twelve Imams, the descendants of the Prophet. However, it is not known on what grounds you attempt to force Muslims to follow the Ash'aris or Mu'tazalis regarding the fundamentals (usul) and one of the four Imams in the articles of the practice (furu') of the faith. Those who do not follow them are called Rafizis.
Since Abu'l-Hasan Ash'ari, Abu Hanifa, Maliki Ibn Anas Muhammad Ibn Idris Shafi'i, and Ahmad Ibn Hanbal were like many other Muslim ulama’ and jurists, and since there is no injunction from the Holy Prophet to follow them, the restriction to follow them alone is an innovation. If I were to make this charge, what would you say in reply?
Hafiz: Since the four Imams possessed a high degree of devotion to Allah, piety, uprightness, and integrity, along with a vast knowledge of jurisprudence, it has become necessary for us to follow them. Well-Wisher: We are not compelled by logic to confine ourselves to follow them alone. Many others of your ulama’ possessed these same qualities. The restriction to follow them alone is an insult to other ulama’ of equal merit.
We cannot be forced to follow any one person or persons without an authoritative instruction from the Holy Prophet. There is no such authorization by the Prophet about your four Imams. So how can you restrict religion to these four schools of law? Shi’as'ism compared to four schools of law Only a few nights ago you called the Shi’as sect "political," and said that since it did not exist during the Prophet's time - that it came into being during Uthman's caliphate - it was unlawful to follow it.
