you missed my final 2 questions.To summarise the sunnah is something the Prophet has done, confirmed. Whilst a hadith is a so called saying of the prophet often reported by one individual to the other.
A hadith at the very most can only be a possibility of being correct. Whilst the sunnah is confirmed to be correct, ma ii fahmte?
The sunnah has always been clear in what it stands for whilst a hadith needed to be understood by it's narrators, (And therefore interpreted in different ways) by following narrators involved in the transmission of the hadith. Thus also why hadith can contradict the Quran.
The sunnah is from Kitab al sunnah, whilst the hadith come from the different hadith collections, for example Sahih al-Bukhari.
I usually have no problem with hadith if they are supported by the Quran, but when they're not I usually argue against them. Here's a verse from Quran I think helps clarify that better
“And if the messenger were to invent any sayings in Our name, We should certainly seize him by his right hand, And We should certainly then cut off the artery of his heart. Nor could any of you withhold him (from Our wrath). But verily this is a Message for the God-fearing” [Quran 69:44-48] "Am I, then, to look unto anyone but God for judgment when it is He who has bestowed upon you from on high this divine writ, clearly spelling out the truth?" [Quran 6:114]
Hopefully this clarifies it more for you.
those are worth the most marks.
