Please be careful with the 'word' sect. The people you have mentioned here are from Ahl-u-Sunnah Rai Barelvia** they are one of, if not the biggest group of Hanafis in the world and Hanafis are the biggest of the four madhabs in numbers** and their 'aqeedah is exactly as per Ahl-u-Sunnah wal Jammat. Their differences are purely on a fiqh basis and their practices are confirmed as acceptable, so long as we do not start to cast our idea or belief on them or pretend to know what their intention is. They are from the sub-group most likely Dawat-e-Islami.
They may follow Qadiriya in tariqa.
I wouldn't say four madhabs. four different schools of thought is more in lines with their idealogy. IMO.
I agree to rest of it.
