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].”

[ذمُّ السّلف لمن ردّ بغير كتابٍ ولا سنّةٍ]
قال شيخ الإسلام ابن تيميّة:
"ولهذا كان السّلفُ إذا قيل:
فلانٌ يرُدُّ على فلانٍ.
قالوا: بكتابٍ وسنّةٍ؟
فإنْ قال: نعم؛ صوّبوهُ.
وإنْ قال: لا؛ قالوا:
ردَّ بدعةً ببدعةٍ"
