Here is a prayer you can say when you feel like losing money:

"O Allah, the Vast in Mercy, the One Who returns the absent, I ask You to compensate me for every loss and provide me with a way out of every distress. O Allah, provide me with lawful sustenance, bless me in it, and grant me blessings and success in my money. Amen."

Recite this prayer with sincerity and belief.
