All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.
The Prophet, sallallaahu ‘alayhi wa sallam, said that this Ummah would be divided into different sects in a Hadeeth on the authority of Abu Hurayrah . [Abu Daawood, others]
We previously dealt with this Hadeeth in Fatwa 10945, in which we stated the criterion for the division. So please refer to it.
As for the Tableeghi Jamaa‘ah, it is not included among these deviant sects. Importantly, it is obligatory to judge them justly.
And Allaah Knows best.
