Shaikh Hassan ibn 'Abdul-Wahhab al-Banna (hafidhahullaah) said that 'Ali ibn Abi Talib (radiallaahu 'anhu) said:
Khawf min Al-Jaleel (Fearing The Noble (Allaah)) Wa 'amal bi Tanzeel (and acting upon Revelation) Wa rida bil kaleel (and being pleased with little) Wa nastaidh li Yawmi raheel (and preparing yourself for the day you will leave this world [die; be buried])

Subhanak Allaahuma wa bihamdika ash-hadu anlaa illaaha illa anta astaghfiruka wa atubu ilayk
If I said anything correct, then it is from Allaah (subhanahu wa taa'ala), and if I erred, then that is from me and shaytan.
