Quran 2:13 Al-Baqarah, ayah 13 of 286

وَإِذَا قِيلَ لَهُمْ ءَامِنُوا۟ كَمَآ ءَامَنَ ٱلنَّاسُ قَالُوٓا۟ أَنُؤْمِنُ كَمَآ ءَامَنَ ٱلسُّفَهَآءُ ۗ أَلَآ إِنَّهُمْ هُمُ ٱلسُّفَهَآءُ وَلَـٰكِن لَّا يَعْلَمُونَ ۝١٣

2:13 And when it is said unto them: believe as the people believe, they say: shall we believe as the foolish believe? are not they indeed the foolish? But they know not.
