Spiritual blindness of disbelievers

قَالُوا۟ يَـٰشُعَيْبُ مَا نَفْقَهُ كَثِيرًا مِّمَّا تَقُولُ وَإِنَّا لَنَرَىٰكَ فِينَا ضَعِيفًا ۖ وَلَوْلَا رَهْطُكَ لَرَجَمْنَـٰكَ ۖ وَمَآ أَنتَ عَلَيْنَا بِعَزِيزٍ

They said, "O Shuʿayb, we do not understand much of what you say, and indeed, we consider you among us as weak. And if not for your family, we would have stoned you [to death]; and you are not to us one respected."

وَقَالُوا۟ يَـٰٓأَيُّهَا ٱلَّذِى نُزِّلَ عَلَيْهِ ٱلذِّكْرُ إِنَّكَ لَمَجْنُونٌ

And they say, "O you upon whom the message has been sent down, indeed you are mad.

وَإِذَا قَرَأْتَ ٱلْقُرْءَانَ جَعَلْنَا بَيْنَكَ وَبَيْنَ ٱلَّذِينَ لَا يُؤْمِنُونَ بِٱلْـَٔاخِرَةِ حِجَابًا مَّسْتُورًا

And when you recite the Qur’ān, We put between you and those who do not believe in the Hereafter a concealed partition.

وَإِذَا تُتْلَىٰ عَلَيْهِمْ ءَايَـٰتُنَا بَيِّنَـٰتٍ قَالَ ٱلَّذِينَ كَفَرُوا۟ لِلَّذِينَ ءَامَنُوٓا۟ أَىُّ ٱلْفَرِيقَيْنِ خَيْرٌ مَّقَامًا وَأَحْسَنُ نَدِيًّا

And when Our verses are recited to them as clear evidences, those who disbelieve say to those who believe, "Which of [our] two parties is best in position and best in association?"

وَمَآ أَنتَ إِلَّا بَشَرٌ مِّثْلُنَا وَإِن نَّظُنُّكَ لَمِنَ ٱلْكَـٰذِبِينَ

You are but a man like ourselves, and indeed, we think you are among the liars.

فَلَمَّا جَآءَهُمُ ٱلْحَقُّ مِنْ عِندِنَا قَالُوا۟ لَوْلَآ أُوتِىَ مِثْلَ مَآ أُوتِىَ مُوسَىٰٓ ۚ أَوَلَمْ يَكْفُرُوا۟ بِمَآ أُوتِىَ مُوسَىٰ مِن قَبْلُ ۖ قَالُوا۟ سِحْرَانِ تَظَـٰهَرَا وَقَالُوٓا۟ إِنَّا بِكُلٍّ كَـٰفِرُونَ

But when the truth came to them from Us, they said, "Why was he not given like that which was given to Moses?" Did they not disbelieve in that which was given to Moses before? They said, "[They are but] two works of magic supporting each other, and indeed we are, in both, disbelievers."
