In part 32, I told you about major Sunni Sects. Then there are sub-sects, groups and movements within Sunnis sects mostly on differences on the following issues First: Reverence of Prophet, Sahaba Companions and Ahle Bait. Second: Powers and knowledge of prophets and saints in life and after their death. Third: Intercession right of humans. Forth: Can someone receive goodness after death by charity or by the recitation of Scripture. Just to give you a brief introduction Barelvi are on the one end of celebrating all that and Wahabi and Salafis on the other extreme of rejecting all that.
