Qur'ān 9:106 · At-Tawbah (التوبة)

وَءَاخَرُونَ مُرْجَوْنَ لِأَمْرِ ٱللَّهِ إِمَّا يُعَذِّبُهُمْ وَإِمَّا يَتُوبُ عَلَيْهِمْ ۗ وَٱللَّهُ عَلِيمٌ حَكِيمٌۭ

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