"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  

“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  

[Machine] The Messenger of Allah ﷺ said, "Indeed, those before you, when one of them committed a sinful act, the one who used to forbid it would warn and admonish them. But when the next day came, he would sit with and eat and drink with him as if he had not seen him commit the sin the day before. So when Allah saw this from them, He caused their hearts to clash with one another, and then cursed them on the tongue of their Prophet Dawud and Isa son of Maryam. This was because of their disobedience and transgression. By the One in whose hand is the soul of Muhammad, you will surely command what is right and forbid what is wrong, and you will surely take action against the oppressor, or Allah will cause your hearts to clash with one another, and then curse you as He cursed them." Khalaf said, "By Allah, you will surely command what is right and forbid what is wrong and oppress them."  

قَالَ رَسُولُ اللهِ ﷺ «إِنَّ مَنْ كَانَ قَبْلَكُمْ كَانُوا إِذَا عَمِلَ الْعَامِلُ مِنْهُمْ بِالْخَطِيئَةِ نَهَاهُ النَّاهِي تعذيرًا حَتَّى إِذَا كَانَ الْغَدُ جَالَسَهُ وَوَاكَلَهُ وَشَارَبَهُ كَأَنَّهُ لَمْ يَرَهُ عَلَى خَطِيئَةٍ بِالْأَمْسِ فَلَمَّا رَأَى اللهُ ذَلِكَ مِنْهُمْ ضَرَبَ قُلُوبَ بَعْضِهِمْ عَلَى بَعْضٍ ثُمَّ لَعَنَهُمْ عَلَى لِسَانِ نَبِيِّهِمْ دَاوُدَ وَعِيسَى ابْنِ مَرْيَمَ ذَلِكَ بِمَا عَصَوْا وَكَانُوا يَعْتَدُونَ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَتَأْمُرُنَّ بِالْمَعْرُوفِ وَلَتَنْهَوُنَّ عَنِ الْمُنْكَرِ وَلَتَأْخُذُنَّ عَلَى يَدَيِ الظَّالِمِ وَلَتَأْطُرُنَّهُ عَلَى الْحَقِّ أَطْرًا أَوْ لَيَضْرِبَنَّ اللهُ قُلُوبَ بَعْضِكُمْ عَلَى بَعْضٍ ثُمَّ لَيَلْعَنَنَّكُمْ كَمَا لَعَنَهُمْ» قَالَ خَلَفٌ تأْطُرُونَهُ تَقْهَرُونَهُ  

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. (Using translation from Abū Dāʾūd 4336)   

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 أَوّلَ ما دخلَ النَّقصُ عَلَى بنِى إِسرائِيلِ، كان الرَّجلُ يلقى الرجل فيقول: يا هذا اتَّقِ اللَّهَ، ودع ما تصنعُ؟ فإِنَّه لا يحِلُّ لك، ثم يلقَاهُ مِنْ الْغدِ فَلا يمْنَعُهُ ذلِكَ أَن يكون أَكيلَه وشرِيبَهُ وقَعِيدَهُ، فلمَّا فعلوا في لِكَ ضَربَ اللَّهُ قلوُب بَعْضِهِمْ ببَعْضٍ كَلَّا وَاللَّه لَتَأمُرُنَّ بالمَعْرُوف وَلَتَنْهَوُنَّ عن المُنكرِ ولتأخُذُنَّ علَى يِّدَىِ الظَّالِم، ولَتأَطِرُنَّه علَى الْحَقِّ أطرًا أو لَيَضرِبَن بقُلُوبِ بَعضِكُم عَلَى بَعضٍ ثمَّ يَلعَنُكُم كمَا لَعَنهم".
