consequences of denying truth

إِنَّمَا يَفْتَرِى ٱلْكَذِبَ ٱلَّذِينَ لَا يُؤْمِنُونَ بِـَٔايَـٰتِ ٱللَّهِ ۖ وَأُو۟لَـٰٓئِكَ هُمُ ٱلْكَـٰذِبُونَ

They only invent falsehood who do not believe in the verses of Allāh, and it is those who are the liars.

قَالَ لَقَدْ عَلِمْتَ مَآ أَنزَلَ هَـٰٓؤُلَآءِ إِلَّا رَبُّ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ بَصَآئِرَ وَإِنِّى لَأَظُنُّكَ يَـٰفِرْعَوْنُ مَثْبُورًا

[Moses] said, "You have already known that none has sent down these [signs] except the Lord of the heavens and the earth as evidence, and indeed I think, O Pharaoh, that you are destroyed."

وَإِذَا ذُكِّرُوا۟ لَا يَذْكُرُونَ

And when they are reminded, they remember not.
