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  

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: "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  

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  

"المدينة حَرَمٌ من كذا إِلى كذا، لا يُقْطَعُ شَجَرُها, ولا يُحْدَثُ فيها حَدَثٌ، من أَحْدَثَ فيها حَدثًا أَو آوى مُحْدثًا فعليه لعنةُ الله والملائكة والناسِ أجمعين، لا يقبل اللهُ منه يوم القيامة صَرْفا ولا عَدْلا".
