There are no sects nor branches in isIam. To say i am sunni, shia, salafi, deobandi, shafi, maturidi, ashari, sufi is going against the command of allah. God in Quran commands us not to divide ourselves into sects. Thus dividing our religion into sects is against God’s command. Those who divide into sects are perceived to commit a wrong where by they have god to deal with Allah as a ré precaution.
Division and sectarianism is a thing brought fourth by man, in the hopes or aim to distinguish from each other. But you will se no division at the core of islam, even in past presented religions.
So at the end of the day a muslim is a muslim without any sub branch or sect
[6:159] Those who divide themselves into sects do not belong with you. Their judgment rests with GOD, then He will inform them of everything they had done.
[30:31] You shall submit to Him, reverence Him, observe the Contact Prayers (Salat), and – whatever you do – do not ever fall into idol worship.
[30:32] (Do not fall in idol worship,) like those who divide their religion into sects; each party rejoicing with what they have.
[42:14] Ironically, they broke up into sects only after the knowledge had come to them, due to jealousy and resentment among themselves. If it were not for a predetermined decision from your Lord to respite them for a definite interim, they would have been judged immediately. Indeed, the later generations who inherited the scripture are full of doubts.
[41:33] Who can utter better words than one who invites to GOD, works righteousness, and says, “I am one of the submitters”?
[2:135] They said, “You have to be Jewish or Christian, to be guided.” Say, “We follow the religion of Abraham—monotheism—he never was an idol worshiper.”
