Mus’ab bin Saad said that Saad used to teach him these words, narrating from the Prophet صلی اللہ علیہ وآلہ وسلم (Allah, I seek refuge with You from miserliness, and I seek refuge with You from cowardice, and I seek refuge with You from reaching the age of senility, and I seek refuge in You from the trials of this world and the torment of the grave.)” (Sahih).
