hardened hearts

وَقَالَ مُوسَىٰ رَبَّنَآ إِنَّكَ ءَاتَيْتَ فِرْعَوْنَ وَمَلَأَهُۥ زِينَةً وَأَمْوَٰلًا فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا رَبَّنَا لِيُضِلُّوا۟ عَن سَبِيلِكَ ۖ رَبَّنَا ٱطْمِسْ عَلَىٰٓ أَمْوَٰلِهِمْ وَٱشْدُدْ عَلَىٰ قُلُوبِهِمْ فَلَا يُؤْمِنُوا۟ حَتَّىٰ يَرَوُا۟ ٱلْعَذَابَ ٱلْأَلِيمَ

And Moses said, "Our Lord, indeed You have given Pharaoh and his establishment splendor and wealth in the worldly life, our Lord, that they may lead [men] astray from Your way. Our Lord, obliterate their wealth and harden their hearts so that they will not believe until they see the painful punishment."

وَأَقْسَمُوا۟ بِٱللَّهِ جَهْدَ أَيْمَـٰنِهِمْ لَئِن جَآءَهُمْ نَذِيرٌ لَّيَكُونُنَّ أَهْدَىٰ مِنْ إِحْدَى ٱلْأُمَمِ ۖ فَلَمَّا جَآءَهُمْ نَذِيرٌ مَّا زَادَهُمْ إِلَّا نُفُورًا

And they swore by Allāh their strongest oaths that if a warner came to them, they would be more guided than [any] one of the [previous] nations. But when a warner came to them, it did not increase them except in aversion

وَإِذَا ذُكِّرُوا۟ لَا يَذْكُرُونَ

And when they are reminded, they remember not.

وَإِذَا رَأَوْا۟ ءَايَةً يَسْتَسْخِرُونَ

And when they see a sign, they ridicule.

وَإِذَا ذُكِرَ ٱللَّهُ وَحْدَهُ ٱشْمَأَزَّتْ قُلُوبُ ٱلَّذِينَ لَا يُؤْمِنُونَ بِٱلْـَٔاخِرَةِ ۖ وَإِذَا ذُكِرَ ٱلَّذِينَ مِن دُونِهِۦٓ إِذَا هُمْ يَسْتَبْشِرُونَ

And when Allāh is mentioned alone, the hearts of those who do not believe in the Hereafter shrink with aversion, but when those [worshipped] other than Him are mentioned, immediately they rejoice.

أَفَلَا يَتَدَبَّرُونَ ٱلْقُرْءَانَ أَمْ عَلَىٰ قُلُوبٍ أَقْفَالُهَآ

Then do they not reflect upon the Qur’ān, or are there locks upon [their] hearts?

حِكْمَةٌۢ بَـٰلِغَةٌ ۖ فَمَا تُغْنِ ٱلنُّذُرُ

Extensive wisdom - but warning does not avail [them].
