The Book Pertaining to the Turmoil and Portents of the Last Hour (Kitab Al-Fitan wa Ashrat As-Sa`ah)
Muslim :: Book 41 : Hadith 6911
Hudhaifa reported: Allah's Messenger (may peace be upon him) informed me of what is going to happen before the approach of the Last Hour. And there is nothing that I did not ask him in this connection except this that I did not ask him as to what would turn the people of Medina out from Medina.
