Unique Punishment for Rejection of Clear Evidence

قَالَ ٱللَّهُ إِنِّى مُنَزِّلُهَا عَلَيْكُمْ ۖ فَمَن يَكْفُرْ بَعْدُ مِنكُمْ فَإِنِّىٓ أُعَذِّبُهُۥ عَذَابًا لَّآ أُعَذِّبُهُۥٓ أَحَدًا مِّنَ ٱلْعَـٰلَمِينَ

Allāh said, "Indeed, I will send it down to you, but whoever disbelieves afterwards from among you - then indeed will I punish him with a punishment by which I have not punished anyone among the worlds."
