Silsilat al-Ahadith al-Sahihah

It is narrated from Mus'ab that Sayyiduna Sa'd (may Allah be pleased with him) used to command five things and would say that the Noble Prophet (peace and blessings be upon him) commanded them: "O Allah! I seek refuge in You from miserliness, I seek refuge in You from cowardice, I seek refuge in You from being returned to feeble old age, I seek refuge in You from worldly trials, and I seek refuge in You from the punishment of the grave." Imam Bukhari (may Allah have mercy on him) has also mentioned "the trial of Dajjal" after the words "worldly trials."
