I do belong to the Sunni sect. But the muslims are slated to be divided into 73 sects until Judgement Day and only one is supposed to be following the righteous path (this is no mere assumption. It actually is the last messenger's prophecy). To be honest, i don't know if I am on the correct path. But what i do know that God and his messenger did gave pretty clear indications to stay on the correct path. These instructions and indications are as crystal clear as signboards at any large airport to lead you to your correct gate to board your aircraft. I hope you understand this example.

These indications include 1. the most truthful form of speech and 2. the best source of guidance. God also did promise his creatures that so long as they seek HIS guidance and righteous path, HE shall provide it to them. It is worth mentioning that God did explicitly mention to his last messenger that you will not succeed in guiding anyone to the rightous path until I wish...so don't use force and too much coercion on people.

The most truthful form of speech becomes the noble Qur'an and the best source of guidance is the lifestyle and practices of the last messenger called the "sunnah".

The followers of the "sunnah" came to be called as the "sunni" and the followers of the prophet's family hierarchy were termed as "Shia"

All i can say is what the Shia's do as muslims is in contrast to what the Qur'an and the "sunnah" recommends.

I know what you wanted to hear on my answer about which of these two sects are correct. Lemme answer it this way.....

The last messenger didn't keep his people in dark about who are the righteous people among those 73sects. He said those who follow me and my ways and takes God's message to the distant places on earth will be the righteous and will be admitted to paradise. So i'd be on the correct path not by enrolling myself to a particular sect but by actually following what is righteous.
