Shia - Sunni issue.

[kılıç_mehmet]

Honestly, this issue, it was something I was obsessed with.

I honestly believe that there is good arguments on both sides.

The Good arguments on Sunni Side is the following:

1) No super ultra clear mention of Imamate of Ali, Hassan and Hussain in Quran or the 12 Imams.
2) Praise of majority of companions in Quran, general praise they will be going to paradise, goes against them almost all turning on their backs after the Prophet.
3) Ali not going to war with Abu Baker and Umar and settling for bad rulers...that were imposed by a few over the rest.
4) Lack of knock out proof in either Quran or Mutuwatir hadiths.

The Good arguments for Shiism:

1) The wage verses, 42:23 combined with 25:57, make it as if the Al-Qurba are the path to God. al-Qurba then obviously means a family of exlated chosen ones.
2) Leaving Two weighty things - Quran and his family, if they hold on to, they will not be misguided, and then in this context states whomever he is Mawla of, then so is Ali. The context is guidance, so Authority makes more sense to mean Mawla. And family is said never to separate from Quran, therefore seem to be sinless (don't disobey God).
3) Hadiths there will be Successors, while only a person inheriting the Guidance position and authority of a Prophet can be a true successor, not just a secular ruler.
4) "We then inherited the book to those whom we chosen of our servants..." in Suratal Fatir.

It seems to me Quran and hadiths give both the impression of Shiism to some, and to others, it gives the impression of Sunnism.

Has anyone here studied the Shia - Sunni dispute and seen arguments on both sides?

Whom do you feel has the better rationalization assuming Islam is true?

Well, I believe that the greatest clashes between sunni and shia is based on the followings:
The slaying of Uthman by a rebel faction within the moslems, and the disputes regarding succession.
The slaying of Ali by another rebel faction within the moslems, and the disputes regarding succession.
The slaying of Ali's children by Muawiyah, and the appointment of his son Yazid as his heir.
And any other Caliph, which has based it's legitimacy from then on, has not been accepted by the Shia moslems as rightful successor, and whatever rulings he had decreed were declared to be unlawful by the shia side.

Indeed, the Shias also refuse to pray in the mosques of the Sunnis, whom they claim to be the very same mosques in which Fatwas regarding Muawiyah's legitimate succession were given to worshippers.
The thing is, the Shia claim that by hadith, that twelve people will succeed Muhammed as legitimate and righteous caliphs.
Until now, there are 11 recognized such individuals, with the twelfth
imam being the person of Mahdi, who will herald the arrival of Jesus Christ on earth.
