Ijmo' al-mujtahidin ta'rif etiladiki, u har qanday davrdagi musulmon ummatining, Payg'ambar ﷺ vafotidan keyin, ahkomlarni chiqarish uchun o'z kuch-g'ayratini sarflaydigan mujtahidlarning yakdil kelishuvidir. Ijmo' al-mujtahidin tarafdorlari Ijmo' al-ummah uchun ishlatiladigan dalilning o'zini ishlatganlar. Shu sababli, Ijmo' al-ummah uchun keltirilgan dalillar Ijmo' al-mujtahidin uchun ham xuddi shunday qo'llanadi.

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.
