'Ali (May Allah be pleased with him) reported:
The Messenger of Allah ﷺ said to me, "Recite: 'Allahumma-hdini wa saddidni (O Allah! Direct me to the Right Path and make me adhere to the Straight Path)." Another narration is: 'Allahumma inni as'aluk-alhuda was-sadad (I beg You for guidance and uprightness)."

[Muslim].

وعن علي رضي الله عنه قال: قال لي رسول الله ﷺ: "قل: اللهم اهدني، وسددني". وفي رواية: "اللهم إني أسألك الهدى، والسداد" ((رواه مسلم)).
