The Prophet (Peace be upon him)  used to say after Fajr prayer: Allahumma Inni As’aluka Rizqan Tayyiban Wa’iliman Naafi’an Wa’amalan Mutaqabbala (O Allah, I ask You for good (Halaal) provision, beneficial knowledge and accepted good deeds). This Dua is general in meaning and includes earnings from business as well as farming, employment or manufacturing. This is how the Sunnah is in Dua that are concise in wording and comprehensive in meaning. But it is Mustahabb for you to ask Allah Ta’ala for what you need by name using whatever simple words and phrases Allah Ta’ala enables you to say.
