Criticising Narrators Without Any Fear
From among the righteous Salaf, there were men, who knew no fear when it came to criticising narrators, regardless whether that man was a ruler or the lowest man in society.
Likewise, they did not fear the blame of anyone, nor did they hesitate to proclaim openly any defect found in narrators.
It was said to Yahyaa Ibn Sa’eed Al-Qattaan:
“Do you not fear that these whose narrations you have abandoned will be your opponents before Allaah on the Day of Judgement?”
For these to be my opponents is more beloved to me than for the Messenger of Allaah (saw) to be my opponent, saying to me, ‘Why did you not expel lies from my hadeeth?‘ “
