does it say that muslims should follow the prophet Mohammed's words and actions? Didnt he himself say NOT to follow his actions? How do muslims justify the credibility of the hadiths? To be quite honest, history books make Mohammed seem like a greater person than the hadiths do... its mind boggling.
===========
Firstly:
Surah 53:
[3] Nor does he say (aught) of (his own) Desire.
[4] It is no less than inspiration sent down to him:
[5] He was taught by one Mighty in Power,
[6] Endued with Wisdom: for he appeared (in stately form)
Secondly, "Hadiths" is a very complicated topic in Islam, latest phenomena resulted from Hadiths is the "Quranists" movement.
Basically, degree of authenticity of a Hadith depends on several factors, Sunni Muslims regard Sahih Bukhari & Sahih Muslim to be the most Authenticated, (sahih = correct),
Both shaikhs followed a unique way in tracing Mo's sayings, they applied strict rules in accepting or rejecting a hadith, and only considered those chains of narrators who meet certain criteria, (eg: honesty, good memory, credibility, etc).
Shaikh Al-albani (died last century), a very prominent Hadith Imam called (muhaddeth), worked nicely to filter hadiths, and extract those Sahih, fair, and other types of authenticity.
The process of classifying Hadiths and their narrators is conducted thru learning something called:
Ilm Al-rejal (science of men).
