The shaikh, Dr. ʿAbdullāh Al-Bukhārī, may Allāh protect him, said:

The Salaf’s Disapproval of Those Who Refute Others without Proofs from the Book and the Sunnah

Shaikh Al-Islām Ibn Taimiyyah said:

Because of this, the Salaf [the righteous, first three generations of this ummah], when it was mentioned that so-and-so had refuted so-and-so, they would [ask]: “With [proofs from the] Book and Sunnah?”

Then if [the one replying] said yes, they’d consider that correct, [but] if he said no, they’d say: “He’s refuted one bidʿah¹ with [another].”
