عن ابن مَسْعُودٍ رضي اللّه عنه قال: قال رسول اللّه صَلّى اللّهُ عَلَيْهِ وسَلَّم: «إِنَّ أَوَّلَ مَا دخَلَ النَّقْصُ عَلَى بَنِي إِسْرائيلَ أَنَّه كَانَ الرَّجُلُ يَلْقَى الرَّجُلَ فَيَقُولُ: يَا هَذَا اتَّق اللّه وَدعْ مَا تَصْنَعُ فَإِنَّهُ لا يَحِلُّ لك، ثُم يَلْقَاهُ مِن الْغَدِ وَهُو عَلَى حالِهِ، فلا يمْنَعُه ذلِك أَنْ يكُونَ أَكِيلَهُ وشَرِيبَهُ وَقعِيدَهُ، فَلَمَّا فَعَلُوا ذَلِكَ ضَرَبَ اللّه قُلُوبَ بَعْضِهِمْ بِبَعْضٍ» ثُمَّ قال: {لُعِنَ الَّذِينَ كَفَرُوا مِنْ بَنِي إِسْرَائِيلَ عَلَى لِسَانِ دَاوُودَ وَعِيسَى ابْنِ مَرْيَمَ ذَلِكَ بِمَا عَصَوْا وَكَانُوا يَعْتَدُونَ (78) كَانُوا لَا يَتَنَاهَوْنَ عَنْ مُنْكَرٍ فَعَلُوهُ لَبِئْسَ مَا كَانُوا يَفْعَلُونَ (79) تَرى كثِيرًا مِنْهُمُ يَتَوَلَّوْنَ الَّذينَ كَفَرُوا لَبِئْسَ مَا قَدَّمتْ لَهُمْ أَنْفُسُهُمْ} إلى قوله: {فَاسِقُونَ} [المائدة:78، 81]؛ ثُمَّ قَالَ: «كَلّا واللّه، لَتَأْمُرُنَّ بالْمعْرُوفِ، وَلَتَنْهوُنَّ عَنِ الْمُنْكَرِ، ولَتَأْخُذُنَّ عَلَى يَدِ الظَّالِمِ، ولَتَأْطِرُنَّهُ عَلَى الْحَقِّ أَطْرًا، ولَتقْصُرُنَّهُ عَلَى الْحَقِّ قَصْرًا، أَوْ لَيَضْرِبَنَّ اللّه بقُلُوبِ بَعْضِكُمْ عَلَى بَعْضٍ، ثُمَّ لَيَلْعَنَنَّكُمْ كَمَا لَعَنَهُمْ» رواه أبو داود، والترمذي وقال: حديث حسن. • هذا لفظ أبي داود، ولفظ الترمذي: قال رسول اللّه صلّى اللّه عليه وسلّم: «لمَّا وَقعَت بنُو إسرائيلَ في المَعاصِي نَهتْهُم عُلماؤُهم فلَمْ يَنتهُوا، فَجالسُوهُم في مَجالسِهِم ووَاكلُوهُم وشاربُوهُم، فضربَ اللّه قلوبَ بعضِهِم بِبعضٍ، ولعنَهُم على لسانِ داوُد وعيسَى ابنِ مريمَ ذلك بما عَصَوْا وكانوا يعتَدُون» فجلس رسول اللّه صلّى اللّه عليه وسلّم وكان مُتكئًا فقال: «لا وَالَّذي نَفْسِي بيدِه حتى تَأْطِرُوهُم على الحقِّ أَطْرًا».

Ibn Mas'ud (may Allah be pleased with him) reported that the Messenger of Allah (peace be upon him) said: "The first deficiency that afflicted the Children of Israel was that a man would meet another and say: 'O you! Fear Allah and abandon what you are doing, for it is not lawful for you.' Then he would meet him the next day while he persisted in the same behavior, yet that would not prevent him from being his eating companion, drinking companion, and sitting companion. When they did this, Allah caused the hearts of some of them to be corrupted by others." Then he recited: "Those among the Children of Israel who disbelieved were cursed by the tongue of David and of Jesus, son of Mary. That was because they disobeyed and used to transgress. They would not forbid one another from the evil they committed. How wretched was what they used to do! You see many of them allying with those who disbelieved. How wretched is what their souls have sent ahead for them..." up to His saying: "...transgressors" [al-Ma'idah: 78-81]. Then he said: "Nay, by Allah! You shall certainly enjoin good, and you shall certainly forbid evil, and you shall certainly restrain the wrongdoer, and you shall certainly compel him to conform to the truth, and you shall certainly confine him to the truth — or else Allah will cause the hearts of some of you to be corrupted by others, and then He will curse you as He cursed them." Narrated by Abu Dawud and al-Tirmidhi, who graded it as a good (hasan) hadith. This is the wording of Abu Dawud. The wording of al-Tirmidhi states: The Messenger of Allah (peace be upon him) said: "When the Children of Israel fell into sins, their scholars admonished them, but they did not desist. Yet the scholars continued to sit with them in their gatherings, and eat and drink with them. So Allah caused the hearts of some of them to be corrupted by others, and cursed them by the tongue of David and of Jesus, son of Mary — that was because they disobeyed and used to transgress." Then the Messenger of Allah (peace be upon him) sat up — he had been reclining — and said: "No! By the One in Whose hand is my soul, [you must continue] until you compel them to conform to the truth."
