I have read in the Malay press, references to the ulama (Muslim scholar) as wakil (representative) of the Prophet of Islam. The word, wakil could mean either a trustee or an agent or delegate as in a principal-agent situation.

In a principal-agent case, the ulama as wakil , is understood to be acting on behalf of another. In this understanding we are asked to accept that the ulama is acting on behalf of the Prophet of Islam. I think this may be where the confusion as to whether the ulama is above mortal scrutiny or not.

If we mean the ulama is trustee, the ulama or any scholar in Islam is expected to use his knowledge and skills to promote the best interests of the community. He exercises independent judgment. His judgement or reasons for arriving at a decision is open to question.

I believe that there is an often used hadith (sayings of the Prophet), but I do not know its level of authenticity, which says that Muslims are to follow those in authority. This, in modern day usage, could not possibly mean that we follow blindly.
