When the Prophet ﷺ went out for (the battle of) Uhud, some of his companions (hypocrites) returned (home). A party of the believers remarked that they would kill those (hypocrites) who had returned, but another party said that they would not kill them. So, this Divine Inspiration was revealed: "Then what is the matter with you that you are divided into two parties concerning the hypocrites." (4.88) The Prophet ﷺ said, "Medina expels the bad persons from it, as fire expels the impurities of iron."  

سَمِعْتُ زَيْدَ بْنَ ثَابِتٍ ؓ يَقُولُ لَمَّا خَرَجَ النَّبِيُّ ﷺ إِلَى أُحُدٍ رَجَعَ نَاسٌ مِنْ أَصْحَابِهِ فَقَالَتْ فِرْقَةٌ نَقْتُلُهُمْ وَقَالَتْ فِرْقَةٌ لاَ نَقْتُلُهُمْ فَنَزَلَتْ {فَمَا لَكُمْ فِي الْمُنَافِقِينِ فِئَتَيْنِ} وَقَالَ النَّبِيُّ ﷺ إِنَّهَا تَنْفِي الرِّجَالَ كَمَا تَنْفِي النَّارُ خَبَثَ الْحَدِيدِ  

Some of the companions of the Prophet ﷺ returned from the battle of Uhud (i.e. refused to fight) whereupon the Muslims got divided into two parties; one of them was in favor of their execution and the other was not in favour of it. So there ware revealed: "Then what is the matter with you that you are divided into two parties about the hypocrites?" (4.88). Then the Prophet ﷺ said "It (i.e. Medina) is a Taybah (good), it expels impurities as the fire expels the impurities of silver."  

رَجَعَ نَاسٌ مِنْ أَصْحَابِ النَّبِيِّ ﷺ مِنْ أُحُدٍ وَكَانَ النَّاسُ فِيهِمْ فِرْقَتَيْنِ فَرِيقٌ يَقُولُ اقْتُلْهُمْ وَفَرِيقٌ يَقُولُ لاَ۔ فَنَزَلَتْ {فَمَا لَكُمْ فِي الْمُنَافِقِينَ فِئَتَيْنِ} وَقَالَ: «إِنَّهَا طَيْبَةُ: تَنْفِي الْخَبَثَ كَمَا تَنْفِي النَّارُ خَبَثَ الْفِضَّةِ۔»  

[Machine] The Messenger of Allah ﷺ went out to Uhud, and some people went out with him. Among the companions of the Messenger of Allah ﷺ were two groups, one group saying that they should be killed and another group saying no. So Allah ﷻ revealed, "What is [the matter] with you [that you are] divided concerning the hypocrites? Allah has cast them back [into disbelief] for what they have earned. Do you wish to guide those whom Allah has sent astray? And he whom Allah sends astray - for him you will never find a way [to guidance]." (Quran 4:88) So the Messenger of Allah ﷺ said, "Verily, it is a good thing and it banishes evil just as fire banishes the impurity of silver."  

أَنَّ رَسُولَ اللهِ ﷺ خَرَجَ إِلَى أُحُدٍ فَرَجَعَ أُنَاسٌ خَرَجُوا مَعَهُ فَكَانَ أَصْحَابُ رَسُولِ اللهِ ﷺ فِيهم فِرْقتان فِرْقَةٌ تَقُولُ بِقَتْلِهِمْ وَفِرْقَةٌ تَقُولُ لَا فَأَنْزَلَ اللهُ ﷻ {فَمَا لَكُمْ فِي الْمُنَافِقِينَ فِئَتَيْنِ} [النساء 88] فَقَالَ رَسُولُ اللهِ ﷺ إِنَّهَا طَيْبَةُ وَإِنَّهَا تَنْفِي الْخَبَثَ كَمَا تَنْفِي النَّارُ خَبَثَالْفِضَّةِ  

[Machine] When the Messenger of Allah ﷺ went out to Uhud, some people came back with him. The companions of the Messenger of Allah ﷺ were divided into two groups. One group said, "Let us kill them," while the other group said, "No." Ibn Ja'far said, "It is better to spare them." So Allah revealed, "What is the matter with you concerning the hypocrites, when Allah has cast them back [to disbelief] for what they earned? Do you wish to guide those whom Allah has sent astray? And he whom Allah sends astray - never will you find for him a way [of guidance]" (Surah An-Nisa, 88). The Messenger of Allah ﷺ said, "It is good and it repels evil just as fire repels the impurities of silver."  

لَمَّا خَرَجَ رَسُولُ اللهِ ﷺ إِلَى أُحُدٍ رَجَعَ أُنَاسٌ خَرَجُوا مَعَهُ فَكَانَ أَصْحَابُ رَسُولِ اللهِ ﷺ فِرْقَتَيْنِ فِرْقَةٌ تَقُولُ نَقْتُلُهُمْ وَفِرْقَةٌ تَقُولُ لَاقَالَ ابْنُ جَعْفَرٍ فَكَانَ فَرِيقٌ يَقُولُونَ قَتْلَهُمْ وَفَرِيقٌ يَقُولُونَ لَا قَالَ بَهْزٌ فَأَنْزَلَ اللهُ {فَمَا لَكُمْ فِي الْمُنَافِقِينَ فِئَتَيْنِ} [النساء 88] فَقَالَ رَسُولُ اللهِ ﷺ إِنَّهَا طَيْبَةُ وَإِنَّهَا تَنْفِي الْخَبَثَ كَمَا تَنْفِي النَّارُ خَبَثَ الْفِضَّةِ  

from Zaid bin Thabit that he heard about this Ayah: Then what is the matter with you that you are divided into two parties about the hypocrites? (4:88) He said: "People among the Companions of the Prophet ﷺ returned on the Day of Uhud and there were two parties among them, a group who said: 'Kill them,' and a group that say not to. So Allah revealed this Ayah: Then what is the matter with you that you are divided into two parties about the hypocrites? (4:88) So he said: "Indeed it is Taibah (Al-Madinah). And he said: 'It expels filth from it just like the fire expels filth from iron.'" (Using translation from Tirmidhī 3028)   

أَنَّهُ قَالَ فِي هَذِهِ الْآيَةِ {فَمَا لَكُمْ فِي الْمُنَافِقِينَ فِئَتَيْنِ وَاللهُ أَرْكَسَهُمْ بِمَا كَسَبُوا} [النساء 88] قَالَ رَجَعَ أُنَاسٌ مِنْ أَصْحَابِ النَّبِيِّ ﷺ فَكَانَ النَّاسُ فِيهِمْ فِرْقَتَيْنِفَرِيقٌ يَقُولُونَ قَتْلَهُمْ وَفَرِيقٌ يَقُولُونَ لَا قَالَ فَنَزَلَتْ هَذِهِ الْآيَةُ {فَمَا لَكُمْ فِي الْمُنَافِقِينَ فِئَتَيْنِ} [النساء 88] وَقَالَ إِنَّهَا طَيْبَةُ وَإِنَّهَا تَنْفِي الْخَبَثَ كَمَا تَنْفِي النَّارُ خَبَثَ الْفِضَّةِ
