Surah Al-Baqarah — Ayah 13 (2:13)
وَإِذَا قِيلَ لَهُمۡ ءَامِنُواْ كَمَآ ءَامَنَ ٱلنَّاسُ قَالُوٓاْ أَنُؤۡمِنُ كَمَآ ءَامَنَ ٱلسُّفَهَآءُۗ أَلَآ إِنَّهُمۡ هُمُ ٱلسُّفَهَآءُ وَلَٰكِن لَّا يَعۡلَمُونَ ١٣
English translation (Saheeh International)
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.
Brief commentary
When they are told to have faith as the companions of Muhammad (peace be upon him) did, they reply, looking down on people and making fun of them, saying “should we have faith like simple-minded people do?” In fact, it is they who are the fools, but they are unaware of this.
