question #1 Sahih Muslim Introduction 54, Introduction, Narration 53 : What impact does a person’s belief have on their credibility in narrating hadiths?

‘The people would transmit from Jābir before there appeared what appeared, then when there appeared what appeared, the people imputed him in his Ḥadīth and some of the people abandoned him’. So it was said to [Sufyān]: ‘What appeared?’ [Sufyān] said: ‘Belief in ar-Raj’ah’.
