وَجَآءَ ٱلْمُعَذِّرُونَ مِنَ ٱلْأَعْرَابِ لِيُؤْذَنَ لَهُمْ وَقَعَدَ ٱلَّذِينَ كَذَبُوا۟ ٱللَّهَ وَرَسُولَهُۥ ۚ سَيُصِيبُ ٱلَّذِينَ كَفَرُوا۟ مِنْهُمْ عَذَابٌ أَلِيمٌ
“Some Bedouins [also] came with excuses, seeking exemption. And those who were untrue to Allah and His Messenger remained behind [with no excuse]. The unfaithful among them will be afflicted with a painful punishment.”
Part of the well-established hypocrites-who-stayed-behind-from-Tabuk passage of Surat al-Tawbah.
