Prayer when we are in need of something

Allahumma inni as'aluka mujibati rahmatika,
wa aza'ima maghfiratika,
wal-ghanimata min kulli birrin,
was-salamata min kulli ithmin,
La tada'li dzanban illa ghafartahu,
wa la hamman illa farajtahu,
wa la hajatan hiya laka ridhan illa qadhaitaha.
Ya arhamar-rahimin.

O God, I ask You to grant me things which will draw me closer to Your mercy,
and which will make Your Forgiveness certain for me,
and a tresure from every virtue,
and protection from every sin,
Please do not leave me with a sin without forgiving it,
and a worry without relieving me of it,
and a need that You are pleased with it without providing it for me,
O the Most Merciful.
