Bukhari :: Book 3 :: Volume 30 :: Hadith 94
Narrated 'Ali:
We have nothing except the Book of Allah and this written paper from the Prophet (where-in 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.
Bukhari :: Book 3 :: Volume 30 :: Hadith 95
Narrated Abu Huraira:
Allah's Apostle said, "I was ordered to migrate to a town which will swallow (conquer) other towns and is called Yathrib and that is Medina, and it turns out (bad) persons as a furnace removes the impurities of iron.
Bukhari :: Book 3 :: Volume 30 :: Hadith 98
Narrated Abu Huraira:
I heard Allah's Apostle saying, "The people will leave Medina in spite of the best state it will have, and none except the wild birds and the beasts of prey will live in it, and the last persons who will die will be two shepherds from the tribe of Muzaina, who will be driving their sheep towards Medina, but will find nobody in it, and when they reach the valley of Thaniyat-al-Wada', they will fall down on their faces dead."
