We have come across some ridiculous posts lately, with Muslims demeaning other Muslims, accusing them to be of certain Islamic groups, and falsely accusing prominent shuyukh to be of particular denominations. Some have escalated to a point that if you happen to like a specific scholar, then you are automatically pigeon-holed to belong to a particular Islamic denomination.
Many Muslims adopt the teachings of a particular mazhab. There are historical and geographical reasons for this. Generally each mazhab follows his interpretation on certain elements of fard, such as the halal and haram, and aspects of salat.
The mazhabs did not differ on the fundamental pillars of our faith, such as tauhid.
