I suggest you read a book called the 'Quran' which is a guide for all mankind. Its all about how to submit yourself to Allah and become a muslim.
(31.006)"But there are, among men, those who purchase idle tales, without knowledge (or meaning), to mislead (men) from the Path of
Allah and throw ridicule (on the Path): for such there will be a Humiliating Penalty."
Please give up all this BS about Sunni and Shia because it is totally irrlevant and detrimental to all concerned. Read the Quran, clear,complete, fully detailed and leave conjecture for the mislead.
What if half of everything you were ever told was a lie, how will you know the truth?
