فَإِن تَوَلَّوْا۟ فَقُلْ ءَاذَنتُكُمْ عَلَىٰ سَوَآءٍۢ ۖ وَإِنْ أَدْرِىٓ أَقَرِيبٌ أَم بَعِيدٌۭ مَّا تُوعَدُونَ
But if they are averse, then say: I have warned you all alike, although I know not whether nigh or far is that which ye are promised.

Sahih al-Bukhari
Virtues of Madinah
Chapter: Haram (sanctuary) of Al-Madina
Narrated `Ali:
We have nothing except the Book of Allah and this written paper from the Prophet (wherein is written:) Medina is a sanctuary from the 'Air Mountain to such and such a place, and whoever innovates in it an heresy or commits a sin, or gives shelter to such an innovator in it will incur the curse of Allah, the angels, and all the people, none of his compulsory or optional good deeds of worship will be accepted. And the asylum (of protection) granted by any Muslim is to be secured (respected) by all the other Muslims; and whoever betrays a Muslim in this respect incurs the curse of Allah, the angels, and all the people, and none of his compulsory or optional good deeds of worship will be accepted, and whoever (freed slave) befriends (take as masters) other than his manumitters without their permission incurs the curse of Allah, the angels, and all the people, and none of his compulsory or optional good deeds of worship will be accepted.
