It is interesting to note that sects follow their own books of hadith, and within their own hadith there are narations that go against their own tenets when they debate against each other.
For example a sunni will be silent on hadith such as:
Sahih Bukhari:
Narrated Jabir bin Samura: I heard Muhammad saying, "There will be twelve Muslim rulers." He then said a sentence which I did not hear. My father said, "All of them (those rulers) will be from Quraish." [1]
Sahih Muslim :
Narrated Jabir bin Samura: I heard Muhammad saying, "The (Islamic) religion will continue until the Hour (day of resurrection), having twelve Caliphs for you, all of them will be from Quraysh."[2]
Sunan Abu Dawood :
The Prophet said: "This religion remains standing until there are twelve vicegerents over you, all of them agreeable to the nation, all of them from Quraysh." [3]
Sunan al-Tirmidhi :
The Prophet said: "There will be after me twelve Amir (Prince/Ruler), all of them from Quraysh." [4]
Musnad Ahmad ibn Hanbal
Masrooq rates that someone asked Abdullah Ibn Masood, "O Abaa Abd al-Rahmaan, did you ask the Messenger of Allah how many caliphs will rule this nation?". Abdullah Ibn Masood replied, "Yes, we did ask the Messenger of Allah and he replied, "Twelve, like the number of chiefs (nuqabaa) of Bani Israel"" [5]
And Shia will be silent on hadith with regards to issue of 'fadak' and inheritance in such as:
This is confirmed in Shia Hadith as well. Let us examine Shia Hadith in Al-Kafi, the most reliable of the four Shia books of Hadith, on the same matter:
'The Prophets did not leave dinars and dirhams as inheritance, but they left knowledge.' (al-Kafi, vol. 1 p. 42)
This Shia Hadith in Al-Kafi has two separate narrations, and is considered Sahih by the Shia. The authenticity is confirmed by Ayatollah Khomeini, who used this Hadith to prove his claim of Wilayah al-Faqih. Khomeini said about the Hadith:
'The narrators of this tradition are all reliable and trustworthy. The father of 'Ali ibn Ibrahim [namely Ibrahim ibn Hashim] is not only reliable, [but in fact] he is one of the most reliable and trustworthy narrators.'
