Al-Khateeb Al-Baghdaadee (d. 463H) cites an isnaad going back to Aboo ‘Abdillaah Muhammad ibn ‘Alee as-Suwaree that he said (in some lines of poetry):

“Say to the one who opposes the hadeeth and sets out
discrediting its people and those who claim it,
‘Are you saying that which you are saying based upon knowledge, my son?
Or upon ignorance? For indeed ignorance is a character of the foolish.
Does one discredit those who have protected the religion
From falsehood and misrepresentation?
And to their statements and to that which they narrated
Returns every scholar and jurist.”
