Aqeedah of Salafis
Q: Some Ulama from the Deobandi school of thought have included the Salafis as a part of Ahlus Sunnah Wal Jamaa'ah and some haven't. They have done this primarily on the basis of Aqeedah. Someone also told me that Moulana Husayn Ahmed Madani had some 'Salafi' beliefs specifically regarding Aqeedah. After some searching I found it to be true. If that is the case, and their Aqeedah is also correct, why should we then regard them as deviated? Isn't it just another valid ikhtilaaf from many.
My second question is that, is there Ijmaa' on the compulsion of following a Mazhab, or is it only for the betterment of this pure Deen of ours?
