Quran At-Tawbah 9:106

وَءَاخَرُونَ مُرۡجَوۡنَ لِأَمۡرِ ٱللَّهِ إِمَّا يُعَذِّبُهُمۡ وَإِمَّا يَتُوبُ عَلَيۡهِمۡۗ وَٱللَّهُ عَلِيمٌ حَكِيمٞ

Translation

And [there are] others deferred until the command of Allāh - whether He will punish them or whether He will forgive them. And Allāh is Knowing and Wise.
