Al-Baqarah - 2:13

وَإِذَا قِيلَ لَهُمْ آمِنُواْ كَمَا آمَنَ النَّاسُ قَالُواْ أَنُؤْمِنُ كَمَا آمَنَ السُّفَهَاء أَلا إِنَّهُمْ هُمُ السُّفَهَاء وَلَـكِن لاَّ يَعْلَمُونَ
[2:13]
And when it is said to them: Believe as the people believe they say: Shall we believe as the fools believe? Now surely they themselves are the fools, but they do not know.
When it is said to them: "Believe as the others believe:" They say: "Shall we believe as the fools believe?" Nay, of a surety they are the fools, but they do not know.
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.
