Verse 5:115

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

“God said, ‘I will indeed send it down to you. But should any of you disbelieve after this, I will indeed punish him with a punishment such as I do not punish anyone in all creation.’”
