قَالَ ٱللَّهُ إِنِّي مُنَزِّلُهَا عَلَيۡكُمۡۖ فَمَن يَكۡفُرۡ بَعۡدُ مِنكُمۡ فَإِنِّيٓ أُعَذِّبُهُۥ عَذَابٗا لَّآ أُعَذِّبُهُۥٓ أَحَدٗا مِّنَ ٱلۡعَٰلَمِينَ

Qaalal laahu innee munaz ziluhaa 'alaikum famai yakfur ba'du minkum fa inneee u'azzibuhoo 'azaabal laaa u'azzibuhooo ahadam minal 'aalameen

Allah said: "I will send it down unto you: But if any of you after that resisteth faith, I will punish him with a penalty such as I have not inflicted on any one among all the peoples."
