Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated from the Messenger of Allah (peace and blessings be upon him), he (peace be upon him) said: "By Him in Whose hand is my soul! The world will not end until a man passes by a grave and says: 'Would that this were my grave!' He will not say this because of religion, but only because of (worldly) hardships."
