Sunan Ibn Majah, Chapter: The Chapters on Tribulations

that the Messenger of Allah (saw) said: that the Messenger of Allah (saw) said:"By the One in Whose Hand is my soul, this world will not pass away until a man will pass by a grave, and will roll on it and say: 'Would that I were in the place of the occupant of this grave!' And the reason for that will not be any religious motive, rather it will be because of calamity."
