Al-Isra 17:49

وَجَعَلْنَا عَلَىٰ قُلُوبِهِمْ أَكِنَّةً أَن يَفْقَهُوهُ وَفِي آذَانِهِمْ وَقْرًا ۚ وَإِذَا ذَكَرْتَ رَبَّكَ فِي الْقُرْآنِ وَحْدَهُ وَلَّوْا عَلَىٰ أَدْبَارِهِمْ نُفُورًا

And We have placed over their hearts coverings, lest they understand it, and in their ears deafness. And when you mention your Lord alone in the Qur'an, they turn back in aversion.

نَّحْنُ أَعْلَمُ بِمَا يَسْتَمِعُونَ بِهِ إِذْ يَسْتَمِعُونَ إِلَيْكَ وَإِذْ هُمْ نَجْوَىٰ إِذْ يَقُولُ الظَّالِمُونَ إِن تَتَّبِعُونَ إِلَّا رَجُلًا مَّسْحُورًا

We are most knowing of how they listen to it when they listen to you and [of] when they are in private conversation, when the wrongdoers say, "You follow not but a man affected by magic."

انظُرْ كَيْفَ ضَرَبُوا لَكَ الْأَمْثَالَ فَضَلُّوا فَلَا يَسْتَطِيعُونَ سَبِيلًا

Look how they strike for you comparisons; but they have strayed, so they cannot [find] a way.

قُلْ كُونُوا حِجَارَةً أَوْ حَدِيدًا

Say, "Be you stones or iron

أَوْ خَلْقًا مِّمَّا يَكْبُرُ فِي صُدُورِكُمْ ۚ فَسَيَقُولُونَ مَن يُعِيدُنَا ۖ قُلِ الَّذِي فَطَرَكُمْ أَوَّلَ مَرَّةٍ ۚ فَسَيُنْغِضُونَ إِلَيْكَ رُءُوسَهُمْ وَيَقُولُونَ مَتَىٰ هُوَ ۖ قُلْ عَسَىٰ أَن يَكُونَ قَرِيبًا

Or [any] creation of that which is great within your breasts." And they will say, "Who will restore us?" Say, "He who brought you forth the first time." Then they will nod their heads toward you and say, "When is that?" Say, "Perhaps it will be soon -

يَوْمَ يَدْعُوكُمْ فَتَسْتَجِيبُونَ بِحَمْدِهِ وَتَظُنُّونَ إِن لَّبِثْتُمْ إِلَّا قَلِيلًا

On the Day He will call you and you will respond with praise of Him and think that you had not remained [in the world] except for a little."
