If a person says he believes only in Quran which is an authentic book to be followed, and says Hadith is so much fabricated that it is not possible to find the true ones and even if so. It is the saying of a human being which has no weightage against the holy Quran which is saying of Allah (SWT). What is the status of such a person?
بسم الله الرحمن الرحيم
A person who believes only on the holy Quran and does not accept the hadith and considers the hadith fabricated he is out of the folk of Islam.
مَّنْ يُطِعِ الرَّسُولَ فَقَدْ أَطَاعَ اللّهَ ً [النساء : 80]
Whoever obeys the Messenger obeys Allah.
It is a fact that the adversaries of Islam have fabricated 3.5 Lakh Hadith and added them to the true hadith. But Almighty Allah created such Ulama who wrote a large number of books on Rijal-e-Hadith and prepared parameters to investigate whether a hadith is true or false. By it one can learn about any hadith whether it is true or false. Hence the saying of the person that it is impossible to find out true hadith is not correct.
Allah knows Best!
