وَآخَرُونَ مُرْجَوْنَ لِأَمْرِ اللَّهِ إِمَّا يُعَذِّبُهُمْ وَإِمَّا يَتُوبُ عَلَيْهِمْ ۗ وَاللَّهُ عَلِيمٌ حَكِيمٌ
“And some others are left for Allah's decision, either to punish them or turn to them in mercy. And Allah is All-Knowing, All-Wise.”
This ayah is part of Surat al-Tawba's Tabuk-era passage addressing the hypocrites and excuse-makers who stayed behind or mocked the campaign, described at this event.
