To Him will be the return of you all; [that is] Allah’s true promise. Indeed, He originates the creation, then He will bring it back that He may reward with justice those who have faith and do righteous deeds. As for the faithless, they shall have boiling water for drink, and a painful punishment because of what they used to defy.
— Ali Quli Qarai
Surah Yunus – Verse 4
4. “To Him will be your return, all together. The promise of Allah is true. Verily He originates the (process of) creation, then He causes it to return, that He may reward with justice those who believe and do righteous deeds; but those who disbelieve, for them shall be a drink from the boiling fluids and a painful chastisement for what they used to reject.”
This verse puts forth both the principle of Resurrection (to Him will be your return), and its probability,
(…He originates the (process of) creation, then He causes it to return…).
This meaning is just like verse 19 of Surah Al-’A‘raf, No. 7 which states:
“…As He brought you forth in the beginning, so shall you return.”
And it also refers to the aim of Resurrection which involves punishment and reward. The verse continues saying:
“…that He may reward with justice those who believe and do righteous deeds; but those who disbelieve, for them shall be a drink from the boiling fluids and a painful chastisement for what they used to reject.”
Therefore, those who are believers and have done good deeds will be rewarded in a just manner, leading them to Paradise. The share of the unbelievers will be a burning liquid made of boiling water that will torture them painfully and they will be kept in Hell forever.
