It is narrated from Hazrat Dhahhak bin Muzahim that he says: A person came to the service of the Messenger of Allah, peace and blessings be upon him. He said, "O Messenger of Allah, peace and blessings be upon him! Who is the greatest ascetic among the people in matters of the world?" The Prophet, peace and blessings be upon him, said: "The one who does not forget graves and decay, who leaves the best of the adornments of the world, who prefers the everlasting over the perishable, who does not count tomorrow as part of his days (of life), and who considers himself among the dead."
