sects

Q: It has been said that our Nabi sallallahu alaihi wasallam has said that Christians have 72 sects and Islam will have 73 sects and only one sect will enter paradise, can anybody say which is that right sect.

Q: What are all the Muslim sects that are not Sunni or Shia? (Not every single group from within each sect but all the sects of Islam that every Muslim group falls into i.e Sunni and Shia.)

Q: My question is that today there are many groups - salafis, deobandis, barelvis, tablighis etc. I as a layman often find it hard to explain the differences between them to my other layman friends. Kindly, I need an answer that I can give to a layman because you know people nowadays argue over these issues in spite of not knowing even basics of tahara or salaah?

Q: My question is about the group called subud latithan. Is this part of culture of Islam and the thikr is with all religions.

Q: I am very confused when it comes to sects in Islam (e.g. Shia, Sunni, Wahhabi). I live in UK and I see a lot of sects in Muslims here. Myself I belong from Sunni/Sufi background. I like to call myself just a Muslim and try to avoid sects. However, when I try to improve my knowledge of Deen, I get confused by the different opinions. Most of the opinions make sense to me as the scholars from every sect tend to come up with valid evidence. After looking at a YouTube clip of Dr Zakir Naik I got even more confused. He says that Quran is against sects (giving reference to the Quran chapter 6 verse 159- "Indeed, those who have divided their religion and become sects - you, [O Muhammad], are not [associated] with them in anything. Their affair is only [left] to Allah; then He will inform them about what they used to do.”) Now my question is if the Quran doesn’t allow sects. Does that mean everyone who calls themselves Sunni Shia Wahhabi is not following the Quran? And if that’s true, then what is the best way to educate myself?
