Musnad Ahmad 2:64

Abu Sa’id and Husayn ibn Muhammad narrated to us, they said: Isra’il narrated to us, from Abu Ishaq, from ‘Amr ibn Maymun, from ‘Umar: That the Prophet, peace and blessings of Allah be upon him, used to seek refuge from five: from miserliness, cowardice, the trial of the chest, the punishment of the grave, and the evil of old age.
