حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ عَدِيِّ بْنِ ثَابِتٍ، قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ يَزِيدَ، يُحَدِّثُ عَنْ زَيْدِ بْنِ ثَابِتٍ، أَنَّهُ قَالَ فِي هَذِهِ الآيَةِ ‏:‏ ‏(‏ فَمَا لَكُمْ فِي الْمُنَافِقِينَ فِئَتَيْنِ ‏)‏ قَالَ رَجَعَ نَاسٌ مِنْ أَصْحَابِ رَسُولِ اللَّهِ صلى الله عليه وسلم يَوْمَ أُحُدٍ ‏.‏ فَكَانَ النَّاسُ فِيهِمْ فَرِيقَيْنِ فَرِيقٌ يَقُولُ اقْتُلْهُمْ ‏.‏ وَفَرِيقٌ يَقُولُ لاَ ‏.‏ فَنَزَلَتْ هَذِهِ الآيَةُ ‏:‏ ‏(‏ فَمَا لَكُمْ فِي الْمُنَافِقِينَ فِئَتَيْنِ ‏)‏ وَقَالَ ‏"‏ إِنَّهَا طِيبَةُ وَقَالَ إِنَّهَا تَنْفِي الْخَبِيثَ كَمَا تَنْفِي النَّارُ خَبَثَ الْحَدِيدِ ‏"‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ وَعَبْدُ اللَّهِ بْنُ يَزِيدَ هُوَ الأَنْصَارِيُّ الْخَطْمِيُّ وَلَهُ صُحْبَةٌ ‏.‏

Narrated 'Abdullah bin Yazid: 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 (PBUH) 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.'" Translation Not Available
