Al-Ma'idah 5:115

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

Qāla l-lahu innī munazziluhā ʿalaykum faman yakfur baʿdu minkum fa-innī uʿadhibuhu ʿadhāban lā uʿadhibuhu aḥadan mina l-ʿālamīna

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."
