Shaykh Saalih Al Fawzan says "And this is for the one who says: That the eemaan is sufficient without having interest for the aqeedah.
This is contradictory because eemaan is not eemaan except if the aqeedah is correct. And if the aqeedah is not correct, then there is no eemaan, and (there is) no deen (religion)."
Now you decide what kind of 'preacher' you are listening to to learn your deen!!!
