وَجَآءَ ٱلْمُعَذِّرُونَ مِنَ ٱلْأَعْرَابِ لِيُؤْذَنَ لَهُمْ وَقَعَدَ ٱلَّذِينَ كَذَبُوا۟ ٱللَّهَ وَرَسُولَهُۥ ۚ سَيُصِيبُ ٱلَّذِينَ كَفَرُوا۟ مِنْهُمْ عَذَابٌ أَلِيمٌ

Some of the dwellers of the desert (who were not able to join the army) came to the Prophet seeking exemption from taking part in the battle. Those who called God and His Messengers liars also stayed home (with those who were truly exempt). The disbelievers will soon receive a painful punishment. - Muhammad Sarwar (English)
