hadiths are a big contraversy in islam.
aurthentic hadiths, although second to the quran, should be followed, but look at this key word, AUTHENTIC, any hadith that cannot prove its authenticity, or is proven falso or even has a chance of being false would be considered weak or rejeted. They have a chain of transmitions, person A told person b who told person c... who heard the prohet say "....
if the chain of transmition doesnt reach the prophet it is cosiered broken, or if 2 cosecutive narrators didnt see each other, living in different places, and or different time, etc. the hadith is considered broken
if there is no chain of transmissions, the hadith is rejected
the hadith is also rejected if one of the people in the chain of transmissions is weak, people say that he is unreliable or that he is a liar, or not good at memorization etc.
in conclusion, hadiths are a good source of faith and should be studied and, if authentic, followed, however, we should do thid CAREFULLY, because there is that possibility that it could be forged and not authentic, in this case its rejected, only if it is proven authentic through detailed analysis then it could, and should, be followed.
a good strategy of the enemies of islam is to bring up a weak or fabricated hadith, to confuse muslims.
Also remember, event the best of hadith books, bukhar, muslims, etc. have some forged hadith, although less thaan the others, but still contain them, and even if some schoalrs say that they are 100% authentic, we should still be careful, only the quran is 100% authentic.
hoped i helped bro, and good luck
