Ijma‟ al Mujtahideen is defined as a unanimous agreement of the Mujtahideen (those who exert their efforts to extract the Ahkaam) of the Muslim community of any period following the death of the Prophet (saw). The proponents of Ijma‟ al Mujtahideen have used the same Daleel, which is used for Ijma‟ al Ummah. Thus the same arguments would apply to Ijma al Mujtahideen.
