Allaahumma 'Aalimal-ghaybi wash-shahaadati faatiras-samaawaati wal'ardh, Rabba kulli shay 'in wa maleekahu, 'ash-hadu 'an laa 'ilaaha 'illaa 'Anta, 'a'oodhu bika min sharri nafsee, wa min sharrish-shaytaani wa shirkihi, wa 'an 'aqtarifa 'alaa nafsee soo 'an, 'aw 'ajurrahu 'ilaa Muslim
O Allah, Knower of the seen and the unseen, Creator of the heavens and the earth, Lord and Sovereign of all things I bear witness that none has the right to be worshipped except You. I take refuge in You from the evil of my soul and from the evil and shirk of the devil, and from committing wrong against my soul or bringing such upon another Muslim.
The Prophet (ﷺ) taught this dua to be recited in the morning, evening and after bed.
