Surah Al-Baqarah 2:13

وَإِذَا قِيلَ لَهُمْ ءَامِنُوا۟ كَمَآ ءَامَنَ ٱلنَّاسُ قَالُوٓا۟ أَنُؤْمِنُ كَمَآ ءَامَنَ ٱلسُّفَهَآءُ ۗ أَلَآ إِنَّهُمْ هُمُ ٱلسُّفَهَآءُ وَلَـٰكِن لَّا يَعْلَمُونَ

And when it is said to them, "Believe as the people have believed," they say, "Should we believe as the foolish have believed?" Unquestionably, it is they who are the foolish, but they know [it] not.

Translation: Saheeh International

Tafsir

When it is said to them ‘Believe as the people believe’ that is as the Companions of the Prophet s They say ‘Shall we believe as fools believe?’ that is as the ignorant do? No we do not follow their way. The exalted One refutes them saying Truly they are the foolish ones but they know this not.
