Arrogance and denial of truth

لِيَكْفُرُوا۟ بِمَآ ءَاتَيْنَـٰهُمْ ۚ فَتَمَتَّعُوا۟ ۖ فَسَوْفَ تَعْلَمُونَ

So they will deny what We have given them. Then enjoy yourselves, for you are going to know.

قَالَ فَأْتِ بِهِۦٓ إِن كُنتَ مِنَ ٱلصَّـٰدِقِينَ

[Pharaoh] said, "Then bring it, if you should be of the truthful."
