خَتَمَ ٱللَّهُ عَلَىٰ قُلُوبِهِمْ وَعَلَىٰ سَمْعِهِمْ ۖ وَعَلَىٰٓ أَبْصَـٰرِهِمْ غِشَـٰوَةٌ ۖ وَلَهُمْ عَذَابٌ عَظِيمٌ
Allah has set a seal upon their hearts and upon their hearing, and over their vision is a veil. And for them is a great punishment.

Indeed, those who disbelieve - it is all the same for them whether you warn them or do not warn them - they will not believe.
وَمِنَ ٱلنَّاسِ مَن يَقُولُ ءَامَنَّا بِٱللَّهِ وَبِٱلْيَوْمِ ٱلْـَٔاخِرِ وَمَا هُم بِمُؤْمِنِينَ
And of the people are some who say, "We believe in Allah and the Last Day," but they are not believers.
يُخَـٰدِعُونَ ٱللَّهَ وَٱلَّذِينَ ءَامَنُوا۟ وَمَا يَخْدَعُونَ إِلَّآ أَنفُسَهُمْ وَمَا يَشْعُرُونَ
They [think to] deceive Allah and those who believe, but they deceive not except themselves and perceive [it] not.
