Hamdulillah, I recall reading concerning the Aqeedah of the Ahl-us-Sunnah wa-l Jama'ah that speaking in praise of, or having admiration for any of the organizations or groups of the Ahl-ul-Bid'ah, is against our Aqeedah. For instance, saying "at least that Group was well organized & protected their leader", while this same Group is a deviant group, even kufr!
But I've been unable to recall which work I read this point in, can anyone help?
