Sahih Bukhari Volume 8, Book 75, Hadith Number 399.

Narated By Sa’d bin Abi Waqqas : The Prophet used to teach us these words as he used to teach us the Book (Qur’an): “O Allah! seek refuge with You from miserliness, and seek refuge with You from cowardice, and seek refuge with You from being brought back to (senile) geriatric old age, and seek refuge with You from the affliction of the world and from the punishment in the Hereafter.”
