The Roots of Al Murji'ah
:The movement of Al Murji'ah started with the appearance of the Khawaarij and the Shi'ites.
The Khawaarij claimed that all the Sahabah were Kaafirs, while some Shi'ites claimed that 'Uthman, Mu'aawiya, 'Aaisha (radiallaahu 'anhum) and many others, were Kaafirs; and at the same time, they gave Ali (Radiallaahu 'anhu) a status much higher than any human.
In between these two positions a third group emerged claiming not to abide to either side by putting off any judgment on either side. This group is definitely in contradiction with the righteous position which believe in, and respect all Companions of the Prophet (salallaahu 'alayhee wa sallam).
The first to proclaim Irjaa' was Bathr Bin 'Abdullah Alhamadani.
This man was put down by the people of his time and they never returned his salaam. Then the Bid'ah of Irjaa' appeared largely in all Koofa (Iraq) and it was represented by people like Mohammad Bin Karram.
Origins of al Murji'ah:
With the appearance of many factions of Al Murji'ah, big differences in their beliefs emerged as well. An example of these factions is Aljabria who believe that humans have no will; while on the other hand, in the field of the Names and Qualities of Allah (Ta'aala), (Al Asmaa wa As Sifat) they negate all the qualities, and some of them believe in the termination of Jannah and Jahannam, and others have dropped so low in their beliefs by judging Allah (Ta'aala) and negated all the Names and disqualified all the Qualities of Allah, pretending to Honour Allah (Subhannah wa Ta'aala).
