﴿ 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!"”

(Allah said) to Jesus, tell them: (Lo! I send it down for you) that which you have asked for. (And whoso disbelieveth of you afterward) after sending it down and eating from it, (him surely will I punish with a punishment wherewith I have not punished any of (My) creatures) of his time: I will turn them into swine. But after they ate from the food, they said: this is clear magic. Jesus said in response: O Allah! If you punish them for what they are saying, they are Your servants; but if you forgive them, You are Mighty in Your retribution towards him who does not repent.
