Al-Ma'idah 5:115

Qala Allahu innee munazziluhaAAalaykum faman yakfur baAAdu minkum fa-innee oAAaththibuhuAAathaban la oAAaththibuhu ahadanmina alAAalameen

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."

Allah said, “I am going to send it down to you; but whoever among you disbelieves after that, I shall give him such a punishment as I shall not give to anyone else in all the worlds.”
