Du'a for lawful provision

اللَّهُمَّ اكْفِنِي بِحَلَالِكَ عَنْ حَرَامِكَ، وَأَغْنِنِي بِفَضْلِكَ عَمَّنْ سِوَاكَ

Allahummak-fini bihalalika 'an haramika, wa aghnini bifadlika 'amman siwak

O Allah, suffice me with Your lawful against Your unlawful, and enrich me by Your grace so that I have no need of anyone besides You.
