Shaikh Muqbil (rahimahullaah) mentioned concerning Shaikh Rab'ea bin Hadee (hafidhahullaah):
...from amongst the individuals who are very knowledgeable about parties and groups during present times is the brother Rabe'a bin Hadee al Mudhkalee (hafidhahullaah). The person who Rabe'a informs is a hizbee, his affair will eventually become apparent and exposed after some time, and you will remember (that Shaikh Rabe'a warned of him).
A person's affair initially is unknown and that individual doesn't want to expose himself, but if he becomes more popular and gains a following and he no longer is worried about what is said concerning him, he exposes what he holds (his true beliefs and methodology).

Subhanak Allaahuma wa bihamdika ash-hadu anlaa illaaha illa anta astaghfiruka wa atubu ilayk
If I said anything correct, then it is from Allaah (subhanahu wa taa'ala), and if I erred, then that is from me and shaytan.
