Quran chapter 3, verse 56

Disbelievers will be severely punished in this world. Allah says in Quran 3:56,

And as for those who disbelieved, I will punish them with a severe punishment in this world and the Hereafter, and they will have no helpers

Let's see what the punishment is for the Disbelievers who disbelieved in Allah and prophet Muhammad. Below are the classical scholary exegesis of the above verse.

Tafsir Ibn Kathir:

This is what Allah did to the Jews who disbelieved in Isa and the Christians who went to the extreme over him. Allah tormented them in this life; they were killed, captured, and lost their wealth and kingdoms. Their torment in the Hereafter is even worse and more severe

Tafsir al-Jalalayn

As for the disbelievers, I will chastise them with a terrible chastisement in this world, through being killed, taken captive and made to pay the jizya, and the Hereafter, in the Fire; they shall haveno helpers, none to protect them from it.

Tafsir Ibn Abbas

(As for those who disbelieve) in Allah and in His messengers Muhammad and Jesus (I shall chastise them with a heavy chastisement in the world) by exposing them to the sword and the capitation tax (jizyah) (and the Hereafter) by throwing them into the Fire; (and they will have no helpers) to save them from Allah's punishment in this world or in the Hereafter.
