Sahih Bukhari Volume 008, Book 075, Hadith Number 381.

Narated By Mus'ab bin Sa'd : Sa'd bin Abi Waqqas used to recommend these five (statements) and say that the Prophet said so (and they are): "O Allah! I seek refuge with You from miserliness, and seek refuge with You from cowardice, and seek refuge with You from being brought back to geriatric old age, and seek refuge with You from the afflictions of the world, and seek refuge with You from the punishment of the grave."
