﴿ قَالَ ٱللَّهُ إِنِّى مُنَزِّلُهَا عَلَيْكُمْ ۖ فَمَن يَكْفُرْ بَعْدُ مِنكُمْ فَإِنِّىٓ أُعَذِّبُهُۥ عَذَابًۭا لَّآ أُعَذِّبُهُۥٓ أَحَدًۭا مِّنَ ٱلْعَٰلَمِينَ ﴾

“God answered: "Verily, I [always] do send it down unto you: and so, if any of you should henceforth deny [this] truth, on him, behold, will I inflict suffering the like of which I have never [yet] inflicted upon anyone in the world!"”

but whoever disbelieves, [whoever] is veiled from this religion after it is sent down and has become clear, I shall surely chastise him with a chastisement wherewith I chastise no other being from among all the worlds', by virtue of the path having become clear and the religion and proof having been clarified and their preparedness existing, so that when they deny it they are doing so only out of obstinacy. Chastisement in the case of knowledge is more intense than chastisement in the case of ignorance, since the sensing of the fact that one is veiled from that [truth] necessitates a severe painfulness [in the chastisement].
