Here comes the most hypocritical foolish Shiite on this website he will definitely give you answers from his own assumptions.😁
Shiism and Sunnism and even Islam are undefined and meaning nothing. All you think by the concept and what you attach to the label, is in your head. It's not real.
Submitting to God is the way, doesn't make Islam true, nor does the fact Muslims testify to Mohammad make him his followers, nor Shiites the followers of Ali, nor Twelvers are automatically representing the twelve because they are right about the number per Quran.
These days, no group has full representation of the truth, only Ahlulbayt have that, and there is only one remaining from the that family.
No one else can claim to understand the Quran fully let alone have referred all disputes back to it from the Sunnah.
We have to work together. And the first thing that has to go, is divisions.
We aren't going to unite on the truth until we allow room for others to be right about somethings and wrong about other. And Islam and Muslims have become just titles like Judaism and Christianity.
Titles and labels don't define anyone. And Mohammad (s) is not a Muslim like us, he is a submitter to God above causing divisions among humans.
If we submit all good, if we don't, then let God judge who does and who doesn't. The word between all of us of all views and backgrounds around the world should be to Worship God alone and not to take fallible leaders as idols by which we twist our morals left right and center and abandon what we know to stick to them.
Shiism and Sunnism are false identities, they mean nothing really and yet those who subscribe to them are holding to sorcery from Iblis regarding it.
Yes you are suppose to follow the Sunnah and Ahlulbayt, but that doesn't make either title legitimate way to split from humans.
There is no need to title oneself over differences and divide into groups. Humanity is One nation, so let God judge between his servants. Fake Prophets come, still, no need to do takfir. Let God judge human and their hearts.
Just discuss what you believe is your view and try just to show what you know without dividing people against one another.
Learn from others, just as you want others to learn from you.
