Sahih Muslim Book 54, Hadith 10
Allah's Messenger, you have done something in the state of your sleep which you never did before, Thereupon he said: Strange it is that some people of my Ummah would attack the House (Ka'ba) (for killing) a person who would belong to the tribe of the Quraish and he would try to seek protection in the House. And when they would reach the plain ground they would be sunk. We said: Allah's Messenger, all sorts of people throng the path. Thereupon he said: Yes, there would be amongst them people who would come with definite designs and those who would come under duress and there would be travellers also, but they would all be destroyed through one (stroke) of destruction. though they would be raised in different states (on the Day of Resurrection). Allah would, however, raise them according to their intention.
They would soon seek protection in this House, viz. Ka'ba (the defenceless), people who would have nothing to protect themselves in the shape of weapons or the strength of the people. An army would be sent to fight (and kill) them and when they would enter a plain ground the army would be sunk in it. Yusuf (one of the narrators) said: It was a people of Syria (hordes of Hajjaj) who had been on that day coming towards Mecca for an attack (on 'Abdulllah b. Zubair) and Abdullah b. Safwan said: By God, it does not imply this army.
You do not see what I am seeing and I am seeing the places of turmoil between your houses as the places of rainfall.
