From the All Inclusive Supplications of the Prophet (ﷺ)

‏
ﻋَﻦْ ﺃَﺑِﻲ ﺑُﺮْﺩَﺓَ، ﻋَﻦْ ﻋَﻠِﻲٍّ، ﻗَﺎﻝَ ﻗَﺎﻝَ ﻟِﻲ ﺭَﺳُﻮﻝُ ﺍﻟﻠَّﻪِ ﺻﻠﻰ ﺍﻟﻠﻪ ﻋﻠﻴﻪ ﻭﺳﻠﻢ ‏ "‏ ﻗُﻞِ ﺍﻟﻠَّﻬُﻢَّ ﺍﻫْﺪِﻧِﻲ  ﻭَﺳَﺪِّﺩْﻧِﻲ ﻭَﺍﺫْﻛُﺮْ ﺑِﺎﻟْﻬُﺪَﻯ ﻫِﺪَﺍﻳَﺘَﻚَ ﺍﻟﻄَّﺮِﻳﻖَ ﻭَﺍﻟﺴَّﺪَﺍﺩِ ﺳَﺪَﺍﺩَ ﺍﻟﺴَّﻬْﻢِ.  ‏

  Ali reported that Allah's Messenger (ﷺ) said to him: Say, "O Allaah, direct me to the right path and make me adhere to the straight path," and when you make a mention of right guidance, keep in mind the right path and when you consider of the straight (path), keep in mind the straightness of the arrow.
