If you seek to define official beliefs of a religion, you are seeking the end of the rainbow. There is no such thing.
I define a Muslim and Islam in this outward world as in the official religion and it's adherent, those with their tongue testify "There is no god but God and Mohammad is his Messenger". This doesn't imply anything about belief, because we dispute what a god is and what Worshiping God alone means, and we even dispute about what Prophethood means and what Messengerhood means, and we dispute of who Mohammad is and his traits and there is probably not a single thing that unites us belief wise if you were to collect all Muslims and ask them their views.
I realized this is true of every religion including Christianity (trinity is not agreed concept for example).
Therefore these discussions about this religion and that religion, are meaningless.
And testifying to Mohammad being the seal of Prophets is different then other Prophets in the sense, they all didn't need to prove WHY they are the last.
And the most hardest proof is to prove exactly why you are last and no Prophet after you, because it seemingly contradicts the need of Prophets through out time.
And I realize Muslims mostly don't care for proofs regarding why Mohammad is the seal of Prophets and why Quran is to be protected and it's good enough Quran says so, because, of course, they believe Quran is to believed dogmatically as opposed to having insights that proves everything it states including the dark enemy of humanity, magic, etc, and proves everything and doesn't want anything taken for granted.
All in all, because my sect has more than anyone else, made the religion into about humans and idol worship so obvious, I can't call to them.
Nor can I assert that I am a reliable means to guide towards the true creed and it's path.
And even if I had knowledge to the depths where not a single thing of the Shariah exists but I see it in Quran, I don't want to be taken as a guide or leader or representative, lest people rely on me instead of the rope of God and the leaders he has chosen, and the legacy they have left behind.
The proof for God's leaders is best done by God. Right now I believe there exist many scriptures through out the earth, some known some unkown, that manifest the truth of God's religion.
I truly believed this when I read the Torah and see how misrepresented it is, and realize an essential contradiction in it which the Quran seeks to give insight to through out it's chapters.
The hadiths are a mess mixed with truth and falsehood, and it's not meant to for everyone to come to them at any stage in their life.
But at the end, the endless stream of insights, you have to find a reliable means to remember who we are through them. Yes, these people will be attributed falsehood which is why I will no longer recommend studying either Quran which is mistranslated to the extent slavery is included in it as justified in the past, beating woman is a translation, etc, or hadiths which are full of evil propaganda as well as insights, and those translating them and interpreting them these days hide essential truths in them.
I don't know what to tell a human anymore and what they can to get guided. I don't know myself.
I just know what I must do for myself, and inshallah, in time, I will learn what I Can do for humanity with my skills, reflections, and capabilities, and I seek refuge that I ever try to take the positon of the name of God and name myself with it as many dark mystics have done in the past and misguided people away from the chosen and set by God like Seth and Enoch.
I am sorry for all calls to an abstract religion with no concrete methodology to attain it's true creeds and ways.
I believe in Mohammad whoever he truly was and I believe in his successors whatever they truly taught, without knowing all they taught, and without claiming to not be confused pertaining to what is attributed to them.
I seek refuge from relying on conjecture, and seek guidance by the Quran and the family of that reminder but don't know the method to really be guided in the mess of Shiism today nor know how to go alone and decipher the truth from the falsehood.
I been over all lazy and haven't given the Quran proper right let alone other religions.
That said, I still seek enlightenment and insights to Quran through Ahlulbayt (as).
I will ask the family when I do not know and not rely one anyone else for insight, lest I hear falsehood without the truth refuting it, and not be presented both the poison and the cure.
God bless you all and may he unite us to appreciate words of Jesus and the truth found in the Torah, and may he make us recite his last recitation whatever it may be, with sincerity.
Good luck all and goodbye.
