وَلَوْ كَانُوا۟ يُؤْمِنُونَ بِٱللَّهِ وَٱلنَّبِىِّ وَمَآ أُنزِلَ إِلَيْهِ مَا ٱتَّخَذُوهُمْ أَوْلِيَآءَ وَلَٰكِنَّ كَثِيرًۭا مِّنْهُمْ فَٰسِقُونَ
And if they had believed in Allah and the Prophet and in what was revealed to him, they would not have taken them as allies; but many of them are defiantly disobedient.
Those among the Children of Israel who disbelieved were cursed by the tongue of Dawud and 'Isa, son of Maryam. That was because they disobeyed (Allah and the Messengers) and were ever transgressing (beyond the bounds)(78)They used not to forbid one another from the evil they committed. Vile indeed was what they used to do (79)You see many of them taking the disbelievers as their friends. Evil indeed is that which they have sent forward before themselves; for that (reason) Allah is wrath with them, and in torment they will abide (80)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 (81)
Allah Cursed the Disbelievers Among the Children of Israel
Allah states that He has cursed the disbelievers among the Children of Israel long ago, and revealed this fact to His Prophets Dawud and 'Isa, son of Maryam. He cursed them because they disobeyed Allah and transgressed against His creatures. Al-'Awfi reported that Ibn 'Abbas said, "They were cursed in the Tawrah, the Injil, the Zabur (Psalms) and the Furqan (Qur'an)." Allah then states that during their time, their habit was that,
كَانُوا لَا يَتَنَاهَوْنَ عَن مُّنكَرٍ فَعَلُوهُ
(They used not to forbid one another from the evil they committed.)
They did not forbid each other from committing sins and the prohibitions. Allah chastised them for this behavior, so that their behavior would not be imitated. Allah said,
لَبِئْسَ مَا كَانُوا يَفْعَلُونَ
(Vile indeed was what they used to do.)
Hadiths that Order Enjoining Righteousness and Forbidding Evil
There are many Hadiths that order enjoining righteousness and forbidding evil. Imam Ahmad recorded that Hudhayfah bin Al-Yaman said that the Prophet ﷺ said,
وَالَّذِي نَفْسِي بِيَدِهِ، لَتَأْمُرُنَّ بِالْمَعْرُوفِ، وَلَتَنْهَوُنَّ عَنِ الْمُنْكَرِ، أَوْ لَيُوشِكَنَّ اللهُ أَنْ يَبْعَثَ عَلَيْكُمْ عِقَابًا مِنْ عِنْدِهِ، ثُمَّ لَتَدْعُنَّهُ فَلَا يَسْتَجِيبَ لَكُم
(By He in Whose Hand is my soul! You will enjoin righteousness and forbid evil, or Allah will send a punishment on you from Him. Then, you will supplicate to Him, but He will not accept your supplication.) At-Tirmidhi also recorded it and said, "This Hadith is Hasan."
Muslim recorded that Abu Sa'id Al-Khudri said that the Messenger of Allah ﷺ said,
مَنْ رَأَى مِنْكُمْ مُنْكَرًا فَلْيُغَيِّرْهُ بِيَدِهِ، فَإِنْ لَمْ يَسْتَطِعْ فَبِلِسَانِهِ، فَإِنْ لَمْ يَسْتَطِعْ فَبِقَلْبِهِ، وَذلِكَ أَضْعَفُ الْإِيمَانِ
(He among you who witnesses an evil, let him change it with his hand, if he cannot do that, then by his tongue, if he cannot do even that, then with his heart, and this is the weakest faith.)
Abu Dawud said that Al-'Urs, meaning Ibn 'Amirah, said that the Prophet ﷺ said,
إِذَا عُمِلَتِ الْخَطِيئَةُ فِي الْأَرْضِ كَانَ مَنْ شَهِدَهَا فَكَرِهَهَا، - وَقَالَ مَرَّةً فَأَنْكَرَهَا - كَانَ كَمَنْ غَابَ عَنْهَا، وَمَنْ غَابَ عَنْهَا فَرَضِيَهَا كَانَ كَمَنْ شَهِدَهَا
(When sin is committed on the earth, then whoever witnesses it and hates - (once he said): forbids it, will be like those who did not witness it. Whoever was absent from it, but agreed with it, will be like …
