The Messenger of Allah ﷺ said: The first defect that permeated Banu Isra'il was that a man (of them) met another man and said: O so-and-so, fear Allah, and abandon what you are doing, for it is not lawful for you. He then met him the next day and that did not prevent him from eating with him, drinking with him and sitting with him. When they did so. Allah mingled their hearts with each other. He then recited the verse: "curses were pronounced on those among the children of Isra'il who rejected Faith, by the tongue of David and of Jesus the son of Mary"...up to "wrongdoers". He then said: By no means, I swear by Allah, you must enjoin what is good and prohibit what is evil, prevent the wrongdoer, bend him into conformity with what is right, and restrict him to what is right.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ أَوَّلَ مَا دَخَلَ النَّقْصُ عَلَى بَنِي إِسْرَائِيلَ كَانَ الرَّجُلُ يَلْقَى الرَّجُلَ فَيَقُولُ يَا هَذَا اتَّقِ اللَّهِ وَدَعْ مَا تَصْنَعُ فَإِنَّهُ لاَ يَحِلُّ لَكَ ثُمَّ يَلْقَاهُ مِنَ الْغَدِ فَلاَ يَمْنَعُهُ ذَلِكَ أَنْ يَكُونَ أَكِيلَهُ وَشَرِيبَهُ وَقَعِيدَهُ فَلَمَّا فَعَلُوا ذَلِكَ ضَرَبَ اللَّهُ قُلُوبَ بَعْضِهِمْ بِبَعْضٍ ثُمَّ قَالَ { لُعِنَ الَّذِينَ كَفَرُوا مِنْ بَنِي إِسْرَائِيلَ عَلَى لِسَانِ دَاوُدَ وَعِيسَى ابْنِ مَرْيَمَ } إِلَى قَوْلِهِ { فَاسِقُونَ } ثُمَّ قَالَ كَلاَّ وَاللَّهِ لَتَأْمُرُنَّ بِالْمَعْرُوفِ وَلَتَنْهَوُنَّ عَنِ الْمُنْكَرِ وَلَتَأْخُذُنَّ عَلَى يَدَىِ الظَّالِمِ وَلَتَأْطُرُنَّهُ عَلَى الْحَقِّ أَطْرًا وَلَتَقْصُرُنَّهُ عَلَى الْحَقِّ قَصْرًا  

"The Messenger of Allah ﷺ said: 'When the Children of Isra'il fell into decline, a man among them would see his brother committing a sin, and prohibit them from it. The next day, what he saw him doing would not prevent him from eating with him, drinking with him, and associating with him. So Allah pitted their hearts against each other, and He revealed about them in the Qur'an, He said: Those among the Children of Isra'il who disbelieved were cursed by the tongue of Dawud and 'Eisa, son of Mariam. That was because they disobeyed and were ever transgressing.' And he recited until he reached: 'And had they believed in Allah, and in the Prophet, and in what has been revealed to him, never would they have taken them as friends; but many of them are rebellious (5:78-81).' He said: "And Allah's Prophet ﷺ was reclining, so he sat up and said: 'No! Not until you take the hand of the wrong-doer and incline him toward the truth.'"  

رَسُولُ اللَّهِ ﷺ إِنَّ بَنِي إِسْرَائِيلَ لَمَّا وَقَعَ فِيهِمُ النَّقْصُ كَانَ الرَّجُلُ فِيهِمْ يَرَى أَخَاهُ عَلَى الذَّنْبِ فَيَنْهَاهُ عَنْهُ فَإِذَا كَانَ الْغَدُ لَمْ يَمْنَعْهُ مَا رَأَى مِنْهُ أَنْ يَكُونَ أَكِيلَهُ وَشَرِيبَهُ وَخَلِيطَهُ فَضَرَبَ اللَّهُ قُلُوبَ بَعْضِهِمْ بِبَعْضٍ وَنَزَلَ فِيهِمُ الْقُرْآنُ فَقَالَ ( لُعِِنَ الَّذِينَ كَفَرُوا مِنْ بَنِي إِسْرَائِيلَ عَلَى لِسَانِ دَاوُدَ وَعِيسَى ابْنِ مَرْيَمَ ذَلِكَ بِمَا عَصَوْا وَكَانُوا يَعْتَدُونَ ) فَقَرَأَ حَتَّى بَلَغَ (وَلَوْ كَانُوا يُؤْمِنُونَ بِاللَّهِ وَالنَّبِيِّ وَمَا أُنْزِلَ إِلَيْهِ مَا اتَّخَذُوهُمْ أَوْلِيَاءَ وَلَكِنَّ كَثِيرًا مِنْهُمْ فَاسِقُونَ ) قَالَ وَكَانَ نَبِيُّ اللَّهِ ﷺ مُتَّكِئًا فَجَلَسَ فَقَالَ لاَ حَتَّى تَأْخُذُوا عَلَى يَدَىِ الظَّالِمِ فَتَأْطِرُوهُ عَلَى الْحَقِّ أَطْرًا حَدَّثَنَا بُنْدَارٌ حَدَّثَنَا أَبُو دَاوُدَ الطَّيَالِسِيُّ وَأَمْلاَهُ عَلَىَّ حَدَّثَنَا مُحَمَّدُ بْنُ مُسْلِمِ بْنِ أَبِي الْوَضَّاحِ عَنْ عَلِيِّ بْنِ بَذِيمَةَ عَنْ أَبِي عُبَيْدَةَ عَنْ عَبْدِ اللَّهِ عَنِ النَّبِيِّ ﷺ مِثْلَهُ

قَالَ رَسُولُ اللهِ ﷺ إِنَّ أَوَّلَ مَا دَخَلَ النَّقْصُ عَلَى بَنِي إِسْرَائِيلَ كَانَ الرَّجُلُ يَلْقَى الرَّجُلَ فَيَقُولُ يَا هَذَا اتَّقِ اللهَ وَدَعْ مَا تَصْنَعُ فَإِنَّهُ لَا يَحِلُّ لَكَ ثُمَّ يَلْقَاهُ مِنَ الْغَدِ فَلَا يَمْنَعُهُ ذَلِكَ أَنْ يَكُونَ أَكِيلَهُ وَشَرِيبَهُ وَقَعِيدَهُ فَلَمَّا فَعَلُوا ذَلِكَ ضَرَبَ اللهُ قُلُوبَ بَعْضِهِمْ بِبَعْضٍ ثُمَّ قَالَ {لُعِنَ الَّذِينَ كَفَرُوا مِنْ بَنِي إِسْرَائِيلَ عَلَى لِسَانِ دَاوُدَ وَعِيسَى ابْنِ مَرْيَمَ ذَلِكَ بِمَا عَصَوْا وَكَانُوا يَعْتَدُونَ} {كَانُوا لَا يَتَنَاهَوْنَ عَنْ مُنْكَرٍ فَعَلُوهُ لَبِئْسَ مَا كَانُوا يَفْعَلُونَ} [المائدة 79] ثُمَّ قَالَ كَلَّا وَاللهِ لَتَأْمُرُنَّ بِالْمَعْرُوفِ وَلَتَنْهَوُنَّ عَنِ الْمُنْكَرِ وَلَتَأْخُذُنَّ عَلَى يَدِ الظَّالِمِ وَلَتَأْطُرُنَّهُ عَلَى الْحَقِّ أَطْرًا وَلَتَقْصُرُنَّهُ عَلَى الْحَقِّ قَصْرًا  

"إِنَّ بَنِى اسْرائيلَ لَمَّا وقَع فيهم النَّقْصُ كَانَ الرَّجُلُ فيهِمْ يَرَى أَخَاهُ

يقَعُ علَى الذَّنْب فَينْهَاهُ عنْهُ، فَإِذَا كَانَ الغَدُ لَمْ يمْنَعْهُ ما رأَى منْهُ أَنْ يَكُونَ أكيلَهُ، وَشَريبَهُ،

وَخَليطَهُ، فَضَرَبَ اللَّهُ قُلُوب بعْضِهِمْ ببَعْضٍ وَنَزَلَ فِيهمْ القرآنُ: {لُعِنَ الَّذِينَ كَفَرُوا مِنْ بَنِي إِسْرَائِيلَ} الآيات، لا. حتَّى تَأخُذُوا عَلَى يَدَى الظَّالِم فَتَأطِرُوه. عَلى الحَقِّ أَطرًا ".
