The Shias prefer some different ahadith, especially the ones narrated by Ali and Fatima rather than the ones by other companions of the Prophet (pbuh) (Abdulwaheed 51).
The ones narrated by Aisha are one of the least preferred due to her opposition to Ali.
This idea of martyr and suffering appear and express in many of Shia’s ritual and demonstration while Sunni rejects to accept this idea (Eckman 34).
Thirdly, Shia and Sunni both acknowledge the idea of “the end times” according to the Quran says, but the Suuni refused to acknowledge the idea about “the Expected and Awaited” Imam which is taught among Shia that he will return one day to prophesy the end of times to his people (Eckman 34).
The Shias have a different way to do the ritual to the Sunni, wudu and salat practices performed by them differ from the ones practiced by the Suuni, for instance of Shias, forehead is placed “onto a piece of hardened clay from Karbala, and not directly onto the prayer mat” when they perform worship (Abdulwaheed 51).
Prayers are often combined by the Shias also, and sometimes only three (instead of five) worshipping is performed per day.
The belief that Shia Imam is divinely inspired came from “the Shia Muslim believe Muhammad designated all 12 sucessors by name and that they inherited a special knowledge of the true meaning of the scripture that was passed through the Prophet’s descendant (Dallal 27).
Secondly, Shia strongly holds the value and the importance of the idea of martyr and suffering (Abdulwaheed 33).
As a result, Abu Bakr won and became the first Imam (Eckman 31).
After Bakr died, there were 2 more Imams, Umar and Uthman, before Sunni decide to select Ali to become the caliph (Abdulwaheed 30).
