Re: sects in Islam :

He also mentioned Zaidiyyah, like the Ja'fariyyah they are a sub-school within the Shi'ah.
I don't know anything else about them though.
I know a little bit about Shi'ahism by googling but I've got a few questions..
I'm interested in knowing what the doctrines are for both Ja'fariyyah and Zaidiyyah, amongst the Ahl us-Sunnah the Qur'aan is the primary source of religion followed by the Prophetic Sunnah which is today found in the form of narrations (Plural. Ahadith, singular. Hadith) in collections called the Sihah Sittah (the Six Authentics), most Sunni Muslims don't rely directly on these for rulings but have followed scholars (past and present) to intrepret them and then followed the rulings of those scholars, these scholars (Mujtahids) were usually Imams of the four schools of judisperence and their students, I guess the Sunni Mujtahids are similar to the Shi'ah Marji'iyyah.
There are some Sunnis who don't abide by the rulings of one School of Jurisprudence but rather take it upon themselves to decide which rulings are in accordance with the doctrines and which are not, they are known as Salafiyyah, they are the Sunni version of the Akhbariyyah *amongst the *Shi'ah, most Sunnis however follow (Taqleed) one of the four schools of jurisprudence/thought like the Usuli Shi'ah follow their Marji'.
Now I know that the Holy Qur'aan is also the primary source for the Shi'ah and I know they also follow their version of the Sunnah of the Prophet PBUH and the Sunnah of their Imams who they consider the his sucessors but what I would like to know is what are the names of their Sunnah/Ahadith collections/books? I know Al-Kafi is one of them but it would be interesting to know how many there are alotgether and what their names are? Also are the Prophetic narrations found within the same collections as the Imamic *narrations or are they found in seperate collections? Do these collections contain *Ahadith on the methods and rulings such as how to pray Salaah, perform wudhu' etc. or did the Marji' derive these rulings from somewhere else? Do the Shi'ah have chains of narration and Ahadith sciences to distinguish the authentic Ahadith from the weak and fabricated? How do they decide which Ahadith is authentic and which not?
Do the Zaidiyyah *have different sources from the *Ja'fariyyah?
I've seen some* Shi'ah's* quote Ahadith from Sunni sources, how's that work if they consider our Ahadith to be inauthentic due to the nature of our narrators in their eyes?
