The Prophet ﷺ said, "Medina is a sanctuary from that place to that. Its trees should not be cut and no heresy should be innovated nor any sin should be committed in it, and whoever innovates in it an heresy or commits sins (bad deeds), then he will incur the curse of Allah, the angels, and all the people." (See Hadith No. 409, Vol 9).  

عَنِ النَّبِيِّ ﷺ قَالَ الْمَدِينَةُ حَرَمٌ مِنْ كَذَا إِلَى كَذَا لاَ يُقْطَعُ شَجَرُهَا وَلاَ يُحْدَثُ فِيهَا حَدَثٌ مَنْ أَحْدَثَ حَدَثًا فَعَلَيْهِ لَعْنَةُ اللَّهِ وَالْمَلاَئِكَةِ وَالنَّاسِ أَجْمَعِينَ  

I said to Anas, "Did Messenger of Allah ﷺ make Medina a sanctuary?" He replied, "Yes, (Medina is a sanctuary from such-and-such place to such-and-such place. It is forbidden to cut its trees, and whoever innovates an heresy in it or commits a sin therein, will incur the curse of Allah, the angels, and all the people." Then Musa bin Anas told me that Anas added, "..... or gives refuge to such an heretic or a sinner..."  

قُلْتُ لأَنَسٍ أَحَرَّمَ رَسُولُ اللَّهِ ﷺ الْمَدِينَةَ قَالَ نَعَمْ مَا بَيْنَ كَذَا إِلَى كَذَا لاَ يُقْطَعُ شَجَرُهَا مَنْ أَحْدَثَ فِيهَا حَدَثًا فَعَلَيْهِ لَعْنَةُ اللَّهِ وَالْمَلاَئِكَةِ وَالنَّاسِ أَجْمَعِينَ قَالَ عَاصِمٌ فَأَخْبَرَنِي مُوسَى بْنُ أَنَسٍ أَنَّهُ قَالَ أَوْ آوَى مُحْدِثًا  

I asked Anas b. Malik whether Messenger of Allah ﷺ had declared Medina as sacred. He said: Yes. (the area) between so and so. He who made any innovation in it, and further said to me: It is something serious to make any innovation in it (and he who does it) there is upon him the curse of Allah, and that of the angels and of all the people, Allah will not accept from him on the Day of Resurrection either obligatory acts or the surpererogatory acts. Ibn Anas said: Or he accommodates an innovator.  

قُلْتُ لأَنَسِ بْنِ مَالِكٍ أَحَرَّمَ رَسُولُ اللَّهِ ﷺ الْمَدِينَةَ قَالَ نَعَمْ مَا بَيْنَ كَذَا إِلَى كَذَا فَمَنْ أَحْدَثَ فِيهَا حَدَثًا قَالَ ثُمَّ قَالَ لِي هَذِهِ شَدِيدَةٌ مَنْ أَحْدَثَ فِيهَا حَدَثًا فَعَلَيْهِ لَعْنَةُ اللَّهِ وَالْمَلاَئِكَةِ وَالنَّاسِ أَجْمَعِينَ لاَ يَقْبَلُ اللَّهُ مِنْهُ يَوْمَ الْقِيَامَةِ صَرْفًا وَلاَ عَدْلاً قَالَ فَقَالَ ابْنُ أَنَسٍ أَوْ آوَى مُحْدِثًا  

Medina is a sacred territory, so he who made any innovation in it. or gave protection to an innovator, there is upon him the curse of Allah, that of the angels and that of all the people. There would not be accepted on the Day of Resurrection either obligatory acts or supererogatory acts from him.  

عَنِ النَّبِيِّ ﷺ قَالَ الْمَدِينَةُ حَرَمٌ فَمَنْ أَحْدَثَ فِيهَا حَدَثًا أَوْ آوَى مُحْدِثًا فَعَلَيْهِ لَعْنَةُ اللَّهِ وَالْمَلاَئِكَةِ وَالنَّاسِ أَجْمَعِينَ لاَ يُقْبَلُ مِنْهُ يَوْمَ الْقِيَامَةِ عَدْلٌ وَلاَ صَرْفٌ  

[Machine] The Messenger of Allah, ﷺ , said, "The city is sacred from here to here. Whoever innovates in it or shelters an innovator has upon him the curse of Allah, the angels, and all the people. Its trees should not be cut down." He also said, "Except for the purpose of feeding camels."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ الْمَدِينَةُ حَرَامٌ مِنْ لَدُنْ كَذَا إِلَى كَذَا فَمَنْ أَحْدَثَ حَدَثًا أَوْ آوَى مُحْدِثًا فَعَلَيْهِ لَعْنَةُ اللهِ وَالْمَلَائِكَةِ وَالنَّاسِ أَجْمَعِينَ لَا يُعْضَدُ شَجَرُهَا قَالَ وَقَالَ الْحَسَنُ إِلَّا لِعَلَفِ بَعِيرٍ  

[Machine] The messenger of Allah ﷺ said: "Al-Madina is a sacred place, from this point to this point. Whoever introduces an innovation therein or shelters an innovator, upon him is the curse of Allah, the angels, and all people. Allah does not accept from him any ransom or compensation." Hammad added: "No weapon of war should be carried in it."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ الْمَدِينَةُ حَرَامٌ مِنْ كَذَا إِلَى كَذَا مَنْ أَحْدَثَ فِيهَا حَدَثًا أَوْ آوَى مُحْدِثًا فَعَلَيْهِ لَعْنَةُ اللهِ وَالْمَلَائِكَةِ وَالنَّاسِ أَجْمَعِينَ لَا يَقْبَلُ اللهُ مِنْهُ صَرْفًا وَلَا عَدْلًا قَالَ حَمَّادٌ وَزَادَ فِيهِ حُمَيْدٌ لَا يُحْمَلُ فِيهَا سِلَاحٌلِقِتَالٍ  

[Machine] The Messenger of Allah ﷺ said: "Whoever introduces something new in Medina, or offers shelter to innovators, or allies with those who oppose the rightful authorities, upon him is the curse of Allah, the angels, and all people. Allah will not accept any of his deeds or efforts."  

قَالَ رَسُولُ اللهِ ﷺ الْمَدِينَةُ مَنْ أَحْدَثَ فِيهَا حَدَثًا أَوْ آوَى مُحْدِثًا أَوْ تَوَلَّى غَيْرَ مَوْالِيهِ فَعَلَيْهِ لَعْنَةُ اللهِ وَالْمَلَائِكَةِ وَالنَّاسِ أَجْمَعِينَ لَا يَقْبَلُ اللهُ مِنْهُ صَرْفًا وَلَا عَدْلًا  

[Machine] "The Messenger of Allah ﷺ said: 'Whoever causes fear to the people of Medina, Allah will cause fear to him. Upon him is the curse of Allah, the angels, and all people. Allah will not accept any compensation or ransom from him on the Day of Judgment.'"  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ أَخَافَ أَهْلَ الْمَدِينَةِ أَخَافَهُ اللهُ ﷻ وَعَلَيْهِ لَعْنَةُ اللهِ وَالْمَلَائِكَةِ وَالنَّاسِ أَجْمَعِينَ لَا يَقْبَلُ اللهُ مِنْهُ يَوْمَ الْقِيَامَةِ صَرْفًا وَلَا عَدْلًا  

Medina is a sacred territory, so he who made any innovation in it. or gave protection to an innovator, there is upon him the curse of Allah, that of the angels and that of all the people. There would not be accepted on the Day of Resurrection either obligatory acts or supererogatory acts from him. (Using translation from Muslim 1371a)  

قَالَ رَسُولُ اللهِ ﷺ الْمَدِينَةُ حَرَمٌ فَمَنْ أَحْدَثَ فِيهَا حَدَثًا أَوْ آوَى مُحْدِثًا فَعَلَيْهِ لَعْنَةُ اللهِ وَالْمَلَائِكَةِ وَالنَّاسِ أَجْمَعِينَ لَا يَقْبَلُ اللهُ مِنْهُ يَوْمَ الْقِيَامَةِ عَدْلًا وَلَا صَرْفًا  

The Prophet ﷺ said, "Medina is a sanctuary from that place to that. Its trees should not be cut and no heresy should be innovated nor any sin should be committed in it, and whoever innovates in it an heresy or commits sins (bad deeds), then he will incur the curse of Allah, the angels, and all the people." (See Hadith No. 409, Vol 9). (Using translation from Bukhārī 1867)   

أَنَّ النَّبِيَّ ﷺ قَالَ إِنَّ الْمَدِينَةَ حَرَمٌ آمِنٌ مِنْ كَذَا إِلَى كَذَا لَا يُقْطَعُ شَجَرُهَا وَلَا يُحْدَثُ فِيهَا حَدَثٌ فَمَنْ أَحْدَثَ فِيهَا حَدَثًا فَعَلَيْهِ لَعْنَةُ اللهِ وَالْمَلَائِكَةِ وَالنَّاسِ أَجْمَعِينَ لَا يُقْبَلُ مِنْهُ صَرْفٌ وَلَا عَدْلٌ  

"مَنْ أَحْدَثَ حَدَثًا، أَوْ آوى مُحْدِثًا، أَوْ ادُّعِى إِلى غَيرِ أَبيه، أَوْ تَوَلَّى غَيرَ مَوَالِيهِ فَعَلَيه لَعْنَةُ اللهِ والْمَلائِكَة والنَّاس أَجمعين لَا يَقْبَلُ الله مِنْهُ يوم الْقِيَامَةِ صَرْفًا ولا عَدْلًا".  

"مَنْ أَخَاف أَهْلَ الْمَدِينة ظَالمًا لَهُمْ أَخَافَهُ اللهُ، وَكَانَتْ عَلَيه لَعْنَةُ اللهِ والْمَلائِكَةِ والنَّاسِ أَجْمَعِينَ، لَا يَقْبَلُ اللهُ مِنْهُ يَوْمَ الْقِيَامَةِ صرْفًا ولا عَدْلًا".  

"عَنْ مرة الهمدانِىِّ قال: قَرَا علينا علىُّ بنُ أبى طالبٍ صَحيفةً قَدْرَ أصْبُعٍ كانت في قرابِ سيفِ رسولِ الله ﷺ وإذا فيها: (إنَّ لِكُلِّ نَبِىٍّ حَرَمًا، وَأنَا أحَرِّم المدينةَ، من أحدثَ فيها حَدثا، أو آوى مُحدِثًا فعليه لعنةُ الله والملائكةِ والناس أجمعين، لا يقبل الله منه صرفًا ولا عدلا) (*) ".  

"عَنِ الحَسَنِ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ: إِنِّى حَرَّمْتُ المَدِيَنةَ كَمَا حَرَّمَ إِبَراهِيمُ مَكَّةَ لَا يُحْمَلُ فِيهَا سِلَاحٌ لِقِتَالٍ: وَمَنْ أَحْدَثَ فِيهَا حَدَثًا أَوْ آوى مُحْدِثًا فَعَلَيْهِ لَعْنَةُ اللَّهِ وَالمَلائِكَةِ والنَّاسِ أَجْمَعِينَ لَا يُقْبَلُ مِنْهُ صَرْفٌ وَلَا عَدْلٌ".
