To remove financial worries and business troubles, worries of low sales and dooming business, recite these verse in abundance throughout the day in ablution or without ablution

Translation: Certainly a Messenger has come to you from among yourselves; grievous to him is your falling into distress, excessively solicitous respecting you; to the believers (he is) compassionate, But if they turn back, say: Allah is sufficient for me, there is no god but He; on Him do I rely, and He is the Lord of mighty power.
