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.

Al-Baqarah 13

وَإِذَا لَقُوا۟ ٱلَّذِينَ ءَامَنُوا۟ قَالُوٓا۟ ءَامَنَّا وَإِذَا خَلَا بَعْضُهُمْ إِلَىٰ بَعْضٍ قَالُوٓا۟ أَتُحَدِّثُونَهُم بِمَا فَتَحَ ٱللَّهُ عَلَيْكُمْ لِيُحَآجُّوكُم بِهِۦ عِندَ رَبِّكُمْ ۚ أَفَلَا تَعْقِلُونَ

And when they meet those who believe, they say, "We have believed"; but when they are alone with one another, they say, "Do you talk to them about what Allāh has revealed to you so they can argue with you about it before your Lord?" Then will you not reason?

Al-Baqarah 76

۞ أَفَتَطْمَعُونَ أَن يُؤْمِنُوا۟ لَكُمْ وَقَدْ كَانَ فَرِيقٌ مِّنْهُمْ يَسْمَعُونَ كَلَـٰمَ ٱللَّهِ ثُمَّ يُحَرِّفُونَهُۥ مِنۢ بَعْدِ مَا عَقَلُوهُ وَهُمْ يَعْلَمُونَ

Do you covet [the hope, O believers], that they would believe for you while a party of them used to hear the words of Allāh and then distort it [i.e., the Torah] after they had understood it while they were knowing?

Al-Baqarah 75

وَمَثَلُ ٱلَّذِينَ كَفَرُوا۟ كَمَثَلِ ٱلَّذِى يَنْعِقُ بِمَا لَا يَسْمَعُ إِلَّا دُعَآءً وَنِدَآءً ۚ صُمٌّۢ بُكْمٌ عُمْىٌ فَهُمْ لَا يَعْقِلُونَ

The example of those who disbelieve is like that of one who shouts at what hears nothing but calls and cries [i.e., cattle or sheep] - deaf, dumb and blind, so they do not understand.

Al-Baqarah 171

وَإِذَا قِيلَ لَهُمُ ٱتَّبِعُوا۟ مَآ أَنزَلَ ٱللَّهُ قَالُوا۟ بَلْ نَتَّبِعُ مَآ أَلْفَيْنَا عَلَيْهِ ءَابَآءَنَآ ۗ أَوَلَوْ كَانَ ءَابَآؤُهُمْ لَا يَعْقِلُونَ شَيْـًٔا وَلَا يَهْتَدُونَ

And when it is said to them, "Follow what Allāh has revealed," they say, "Rather, we will follow that which we found our fathers doing." Even though their fathers understood nothing, nor were they guided?

Al-Baqarah 170
