'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]. (ID)
