This issue is a most important in issues of informed reasoning (ijtihaad) and imitation (taqliid) in principles of Islamic jurisprudence, so. Is all one of independent legist (mujtahid) right or the truth is just one among the different saying, that the right mujtahid have two compenstaions but the wrong mujtahid have one compenstaion on his ijtihaad. The scholars have two different views about that, the first one which says: only one among the mujtahids is right, that's the view's of majority of scholars, and second one which chosen by Imam Ghazali it's says: all mujtahids are right, However. After discussing the evidence of the two views we find out the first is more correct than the second because of the strength of its evidence.
