Ibn ‘Abbas said “When the verse “If there are twenty amongst you patient and persevering, they will vanquish two hundred” was revealed. It was heavy and troublesome for Muslims when Allaah prescribed for them that one (fighting Muslim) should not fly from ten (fighting Non-Muslims). Then a light commandment was revealed saying “For the present Allaah hath lightened your (task).” The narrator Abu Tawbah recited the verse to “they will vanquish two hundred.” When Allaah lightened the number, patient and perseverance also decreased according to the number lightened from them.”  

نَزَلَتْ { إِنْ يَكُنْ مِنْكُمْ عِشْرُونَ صَابِرُونَ يَغْلِبُوا مِائَتَيْنِ } فَشَقَّ ذَلِكَ عَلَى الْمُسْلِمِينَ حِينَ فَرَضَ اللَّهُ عَلَيْهِمْ أَنْ لاَ يَفِرَّ وَاحِدٌ مِنْ عَشَرَةٍ ثُمَّ إِنَّهُ جَاءَ تَخْفِيفٌ فَقَالَ { الآنَ خَفَّفَ اللَّهُ عَنْكُمْ } قَرَأَ أَبُو تَوْبَةَ إِلَى قَوْلِهِ { يَغْلِبُوا مِائَتَيْنِ } قَالَ فَلَمَّا خَفَّفَ اللَّهُ تَعَالَى عَنْهُمْ مِنَ الْعِدَّةِ نَقَصَ مِنَ الصَّبْرِ بِقَدْرِ مَا خَفَّفَ عَنْهُمْ  

[Machine] "When this verse was revealed: 'If there are twenty of you who are patient, they will overcome two hundred,' Allah commanded them not to flee if the twenty were from the two hundred, so Allah revealed: 'Now Allah has eased the hardship upon you, knowing that there is weakness among you. If there are a hundred of you who are patient, they will overcome two hundred.' So He eased it for them and commanded them not to flee if a hundred were from the two hundred."  

لَمَّا نَزَلَتْ هَذِهِ الْآيَةُ {إِنْ يَكُنْ مِنْكُمْ عِشْرُونَ صَابِرُونَ يَغْلِبُوا مِائَتَيْنِ} فَكَتَبَ عَلَيْهِمْ أَنْ لَا يَفِرَّ الْعِشْرُونَ مِنَ الْمِائَتَيْنِ فَأَنْزَلَ اللهُ ﷻ {الْآنَ خَفَّفَ اللهُ عَنْكُمْ وَعَلِمَ أَنَّ فِيكُمْ ضَعْفًا فَإِنْ يَكُنْ مِنْكُمْ مِائَةٌ صَابِرَةٌ يَغْلِبُوا مِائَتَيْنِ} فَخَفَّفَ عَنْهُمْ وَكَتَبَ عَلَيْهِمْ أَنْ لَا يَفِرَّ مِائَةٌ مِنْ مِائَتَيْنِ  

[Machine] A man does not escape from ten, nor do a group escape from their equal number. So, it was difficult for these people and it was hard on them. Then the verse was revealed, "Now Allah has lightened [the hardship] for you, and He knows that among you is weakness. So if there are from you one hundred [who are] steadfast, they will overcome two hundred." So, they were commanded that no man should run away from two men, nor should a group run away from its equal number. Ibn Abbas said, "So, the patience decreased in proportion to the decrease in their numbers. This is the wording of the Hadith of Affan, and in the narration of Abdullah Ibn Al-Mubarak, it was difficult for the Muslims when it was prescribed that not even one man should flee from ten. Then the relief came, and Allah said, "Now Allah has lightened [the hardship] for you" [Surah Al-Anfal 66]. So, when Allah lightened the number for them, the patience decreased in proportion to what was decreased from them.  

لَا يَفِرَّ رَجُلٌ مِنْ عَشَرَةٍ وَلَا قَوْمٌ مِنْ عَشْرِ أَمْثَالِهِمْ فَجَهَدَ ذَلِكَ النَّاسَ وَشَقَّ عَلَيْهِمْ فَنَزَلَتْ {الْآنَ خَفَّفَ اللهُ عَنْكُمْ وَعَلِمَ أَنَّ فِيكُمْ ضَعْفًا فَإِنْ يَكُنْ مِنْكُمْ مِائَةٌ صَابِرَةٌ يَغْلِبُوا مِائَتَيْنِ} قَالَ فَأُمِرُوا أَنْ لَا يَفِرَّ رَجُلٌ مِنْ رَجُلَيْنِ وَلَا قَوْمٌ مِنْ مِثْلَيْهِمْ قَالَ ابْنُ عَبَّاسٍ فَنَقَصَ مِنَ الصَّبْرِ بِقَدْرِ مَا خَفَّفَ مِنَ الْعِدَّةِ هَذَا لَفْظُ حَدِيثِ عَفَّانَ وَفِي رِوَايَةِ عَبْدِ اللهِ بْنِ الْمُبَارَكِ فَشَقَّ ذَلِكَ عَلَى الْمُسْلِمِينَ حِينَ فُرِضَ أَنْ لَا يَفِرَّ وَاحِدٌ مِنْ عَشَرَةٍ فَجَاءَ التَّخْفِيفُ فَقَالَ {الْآنَ خَفَّفَ اللهُ عَنْكُمْ} [الأنفال 66] الآية فَلَمَّا خَفَّفَ اللهُ عَنْهُمْ مِنَ الْعِدَّةِ نَقَصَ مِنَ الصَّبْرِ بِقَدْرِ مَا خَفَّفَ عَنْهُمْ
