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.
We have already discussed the subject of Islamic groups and the ruling on affiliation to them and on serving Islam through their channels in Fataawa: 88772, 91463 and 82024.

Allaah Knows best.
