Re: Tablighi Jamaat
The context of word orthodoxy I’m talking here means the early traditions of Islam. Similar to the menaing of Orthodox Christianity etc.
Well, there is a whole background to each movement, for example, Brelvi fiqh was created to refute Wahabism, they didn’t name themselves Brelvis but the incidents led that way where those Hindustani Sunnis became famous by this title.
Shias called themselves Ali’s Party. Ismailis and Aga Khanis splited from Shias because they had totally different Aqeedah than Shias and Sunnis.
Now how the four major sunni schools of thought were developed, for that I have given you a link to read the background and everything.
