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  

“When the Children of Isral became deficient in religious commitment, a man would see his brother committing sin and would tell him not to do it, but the next day, what he had seen him do did not prevent him from eating or drinking with him, or mixing with him. So Allah made the hearts of those who did not commit sin like the hearts of those who did, and He revealed Qur’an concerning them and said: “Those among the Children of Israel who disbelieved were cursed by the tongue of David and ‘Eisa, son of Maryam” 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 (the disbelievers) as their friends; but many of them are disobedient (to Allah).”[5:78-81] The Messenger of Allah ﷺ sat up and said: "No, not until they take the hand of the wrongdoer (i.e. restrain him] and force him to follow the right way."  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ بَنِي إِسْرَائِيلَ لَمَّا وَقَعَ فِيهِمُ النَّقْصُ كَانَ الرَّجُلُ 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 {لُعِنَ الَّذِينَ كَفَرُوا مِنْ بَنِي إِسْرَائِيلَ عَلَى لِسَانِ دَاوُدَ وَعِيسَى ابْنِ مَرْيَمَ} حَتَّى بَلَغَ {وَلَوْ كَانُوا يُؤْمِنُونَ بِاللَّهِ وَالنَّبِيِّ وَمَا أُنْزِلَ إِلَيْهِ مَا اتَّخَذُوهُمْ أَوْلِيَاءَ وَلَكِنَّ كَثِيرًا مِنْهُمْ فَاسِقُونَ } قَالَ وَكَانَ رَسُولُ اللَّهِ ﷺ مُتَّكِئًا فَجَلَسَ وَقَالَ لاَ حَتَّى تَأْخُذُوا عَلَى يَدَىِ الظَّالِمِ فَتَأْطِرُوهُ عَلَى الْحَقِّ أَطْرًا حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا أَبُو دَاوُدَ أَمْلاَهُ عَلَىَّ حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي الْوَضَّاحِ عَنْ عَلِيِّ بْنِ بَذِيمَةَ عَنْ أَبِي عُبَيْدَةَ عَنْ عَبْدِ اللَّهِ عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ

"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 ".
