47وَإِنَّ لِلَّذينَ ظَلَموا عَذابًا دونَ ذٰلِكَ وَلٰكِنَّ أَكثَرَهُم لا يَعلَمونَAli UnalAnd surely for those who commit the greatest wrong (through unbelief or associating partners with God, and resisting the conveying of His Religion), there is another punishment besides that; but most of them do not know.1The Day mentioned in verse 45 may be referring either to the day when the leaders of unbelief will be struck dead in the world in a war (as the leaders of the Quraysh were killed in the Battle of Badr) or in another catastrophe, or to the overall destruction of the world. So another punishment mentioned in verse 47 is both the kind of punishment they will be made to suffer in the world so that they may repent, and the punishment in the grave that they will suffer until the Day of Resurrection.
