Musnad Ahmad 1585

It was narrated from Sa’d bin Abi Waqqas that he used to enjoin reciting these five and he narrated them from the Messenger of Allah (ﷺ): “O Allah, I seek refuge with You from miserliness, I seek refuge with You from cowardice, I Seek refuge with You from being sent back to senility (cf. 16:70), I seek refuge with You from the trials of this world, and I seek refuge with You from the punishment of the grave."
