At Tawbah Ayah 90

وَجَآءَ ٱلْمُعَذِّرُونَ مِنَ ٱلْأَعْرَابِ لِيُؤْذَنَ لَهُمْ وَقَعَدَ ٱلَّذِينَ كَذَبُواْ ٱللَّهَ وَرَسُولَهُۥ‌ۚ سَيُصِيبُ ٱلَّذِينَ كَفَرُواْ مِنْهُمْ عَذَابٌ أَلِيمٌ ٩٠ Some nomadic Arabs ?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.
