Umm Salamah (Radhi Allaahu anha) narrated that the Prophet (pbuh) used to say after the dawn prayer,
“Allaahumma inni as’aluka ‘ilman naafi’an, wa rizqan tayyiban, wa ‘amalan mutaqabbalan.”
“O Allaah, I ask You for beneficial knowledge, acceptable action, and good provision.”
[Tirmidhi 2487, Ahmad and Ibn Majah]
