“The one who reject the statements of the well known scholars is deemed a hizbi.”
Shaykh Ahmad Ibn Yahyaa an-Najmi (Rahimahullah) said:
‘Verification is obligatory when it comes to the narration of the faasiq, and as for the narration of the trustworthy person, then it is to be taken. So how much more so if the narrators were a group?
And from the best of people in society? And from its most eminent and most excellent in knowledge and trustworthiness? It is then incumbent to accept the narration; and whomsoever rejects it, has indeed rejected it due to a desire within himself. So, he is blamed and deemed a hizbi (bigoted partisan) as a result of this rejection. He should be counted among them and considered one of them. And with Allah lies all success.’
