Sahih Muslim Book 41, Hadith Number 6959.

Chapter : The Last Hour would not come until a person would pass by a grave and wish that he should have been the occupant of that grave because of this calamity.

Abu Huraira reported Allah’s Messenger (may peace be upon him) as saying: The Last Hour would not come until the Muslims fight with the Turks-a people whose faces would be like hammered shields wearing clothes of hair and walking (with shoes) of hair.
