اللَّهُمَّ بَارِكْ لِي فِي رِزْقِي، وَقَنِّعْنِي بِمَا رَزَقْتَنِي
Allahumma barik li fi rizqi, wa qanni'ni bima razaqtani
O Allah, bless my provision for me and make me content with what You have provided me.
Reference: Al-Bayhaqi
O Allah, I ask You of Your bounty and mercy, for none possesses them but You.
My Lord, expand for me my chest, ease for me my task, and untie the knot from my tongue so they may understand my speech.
O Allah, suffice me with what You have made lawful against what You have made unlawful, and enrich me by Your bounty so I need none but You.
My Lord, indeed I am in need of whatever good You send down to me.
O Allah, I ask You for beneficial knowledge, pure provision, and accepted deeds. (Said after Fajr prayer)
If you were to rely upon Allah with true reliance, He would provide for you as He provides for the birds.
