Sahih Muslim Book 41, Hadith Number 6973.

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 that Allah’s Messenger (may peace be upon him) said: (Khusrau king of Persia) would die and Qaisar (Ceasar King of Rome) would die; there would be no Qaisar after him, but, by one in Whose Hand is my life, you would spend their treasures in the cause of Allah.
