اللهم اكفني بحلالك عن حرامك، واغنني بفضلك عمن سواك
Allāhumma ikfinī bi-ḥalālika ʿan ḥarāmika wa aghninī bi-faḍlika ʿamman siwāk
A prayer for sufficiency from lawful gain, freedom from need of the forbidden, and enrichment by God’s grace alone; said before any enterprise or day of work.
What it means
The supplication asks God for three things: enough from what is lawful (ḥalāl) so that no need of the forbidden arises, freedom from dependence on anyone other than God, and enrichment from His grace. A Muslim says it before beginning an enterprise or a day of productive work. It rests on the Quranic command, “Eat of what is lawful and good on the earth” (2:168), and on the belief that provision comes from God. The prayer is the usual dua for lawful earning.
