These sect driven Muslims believe in the 5 pillars of Islam. This is the biggest lie. There should be like 200+ pillars of Islam. You break one pillar, commit one sin, you become a disbeliever until your repent.
You believe that if you commit one sin your a Kafir?
Indeed.
You don't have to take my word for it, just read up on the Quran and how Allah views sin and Aggregation. At that moment you commit sin, you become a disbeliever unless you repent or not do the sin again. Islam is called "submission". You do not submit to Allah by committing sins. If you commit sins without repentance you are not a submitter therefore you are not of the religion of submission (Islam).
The Quran is all there is to follow. To disregard those clear verses would be some kind of serious dishonesty. I don't know how anyone can stay a Sunni, Shia Muslim after reading the Quran, fortunately, Allah explains this:
[43:36] Anyone who disregards the message of the Most Gracious, we appoint a devil to be his constant companion.
[43:37] Such companions will divert them from the path, yet make them believe that they are guided.
