Allah said, "Indeed, I will sent 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."
قَالَ اللَّهُ إِنِّي مُنَزِّلُهَا عَلَيْكُمْ ۖ فَمَنْ يَكْفُرْ بَعْدُ مِنْكُمْ فَإِنِّي أُعَذِّبُهُ عَذَابًا لَا أُعَذِّبُهُ أَحَدًا مِنَ الْعَالَمِينَ
