The Messenger of Allah used to say: "Allahumma inni a'udhu bika minal-'ajzi, wal-kasali, wal-bukhli, wal-harami, 'adhabil-qabr wa fitnatil-mahya wal-mamat (O Allah, I seek refuge in You from incapacity and laziness, and miserliness and old age, and the torment of the grave, and the trials of life and death.)"
Sunan an-Nasa'i Book 50, Hadith 21
