Qutaybah ibn Sa'id narrated to us, from Malik ibn Anas, in what was read to him, from Abu al-Zinad, from al-A'raj, from Abu Hurayrah, that the Messenger of Allah, peace and blessings be upon him, said: "The Hour will not come until a man passes by the grave of another man and says, 'Would that I were in his place.'"
