Allāhumma raḥmataka arjū falā takilnī ilā nafsī ṭarfata `ayn, wa aṣliḥ lī sha'nī kullah, lā ilāha illā ant. O Allah, I hope for Your mercy. Do not leave me to myself even for the blinking of an eye (i.e. a moment). Correct all of my affairs for me. There is none worthy of worship but You. Reference: Abu Dawud 4/324, Ahmad 5/42. Al-Albani graded it as good in Sahih Abu Dawud 3/959.
