The Farewell Pilgrimage of the Prophet Muhammed was a significant historical event in the Muslims life.
Although thousands of Muslims witnessed the Farewell Sermon given by the Prophet, the Hadiths books reported at least three versions of the same Sermon. This only reflects how confusing, misleading, distorted and inaccurate are the Hadiths Books.
The most notable difference is near the end of the sermon, where Muhammad stated that he leaves behind two things.
One version, for instance, has the statement: "I leave with you Qur'an and Sunnah." The other version has the statement: "I leave with you Qur'an and Ahl al-bayt" (the family of Muhammad). The third version has the statement: "I leave for you the Qur'an, you shall uphold it."
These differences have theological significance for Sunni and Shia followers.
Sunnis hold themselves as the followers of the sunnah or practice of Muhammad as related by his companions, the Sahaba. Sunnis also maintain that the Islamic community, or ummah, as a whole will always be guided.
The Shi'ites hold the second version of the sermon as the correct one. According to Shi'a belief, the only legitimate leadership rested in the lineage of Muhammad's cousin and son-in-law, Ali ibn Abi Talib. The Shi'ites believe that the rest of the Muslim community committed a grave error by electing Abu Bakr and his two successors as leaders.
Only the third version that talks about QURAN ALONE is the only one that does not contradict the QURAN and does not have any political motive behind it. It is the version ignored by the sects of the Sunnites and Shiites because it does not support their political agenda. See Sahih Muslim, Book of Hajj, Book 7 , Number 2803:http://www.iiu.edu.my/deed/hadith/muslim/007_smt.html :
...I have left among you the Book of Allah, and if you hold fast to it, you would never go astray. And you would be asked about me (on the Day of Resurrection), (now tell me) what would you say? They (the audience) said: We will bear witness that you have conveyed (the message), discharged (the ministry of Prophethood) and given wise (sincere) counsel. He (the narrator) said: He (the Holy Prophet) then raised his forefinger towards the sky and pointing it at the people (said): "O Allah, be witness. 0 Allah, be witness," saying it thrice....
Thank you and may God guide us,
