Surah At-Tawba · سُوْرَةُ التَّوْبَةِ · Juz 10
Q 9:90
وَجَآءَ ٱلْمُعَذِّرُونَ مِنَ ٱلْأَعْرَابِ لِيُؤْذَنَ لَهُمْ وَقَعَدَ ٱلَّذِينَ كَذَبُوا۟ ٱللَّهَ وَرَسُولَهُۥ ۚ سَيُصِيبُ ٱلَّذِينَ كَفَرُوا۟ مِنْهُمْ عَذَابٌ أَلِيمٌ
Translations
And those with excuses among the bedouins came to be permitted [to remain], and they who had lied to Allah and His Messenger sat [at home]. There will strike those who disbelieved among them a painful punishment.Et parmi les Bédouins, certains sont venus demander d'être dispensés (du combat). Et ceux qui ont menti à Allah et à Son messager sont restés chez eux. Un châtiment douloureux affligera les mécréants d'entre eux.Tafsir
A group of people from the desert Arabs of Medina and the surrounding areas came with excuses to Allah’s Messenger (peace be upon him), so that he would give them permission to remain behind from going out and striving in Allah’s path. Another group of people who did not even make any excuse also stayed behind from going out because they did not accept the Prophet and they did not have faith in Allah’s promise. A painful punishment will afflict these people because of their disbelief.
