Stubbornness and Spiritual Blindness

وَقَالَ ٱلَّذِينَ لَا يَعْلَمُونَ لَوْلَا يُكَلِّمُنَا ٱللَّهُ أَوْ تَأْتِينَآ ءَايَةٌ ۗ كَذَٰلِكَ قَالَ ٱلَّذِينَ مِن قَبْلِهِم مِّثْلَ قَوْلِهِمْ ۘ تَشَـٰبَهَتْ قُلُوبُهُمْ ۗ قَدْ بَيَّنَّا ٱلْـَٔايَـٰتِ لِقَوْمٍ يُوقِنُونَ

Those who do not know say, "Why does Allāh not speak to us or there come to us a sign?" Thus spoke those before them like their words. Their hearts resemble each other. We have shown clearly the signs to a people who are certain [in faith].

بَلْ قَالُوا۟ مِثْلَ مَا قَالَ ٱلْأَوَّلُونَ

Rather, they say like what the former peoples said.

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."
