أَللَّهُمَّ اكْفِنِى بِحَلاَلِكَ عَنْ حَرَامِكَ وَأَغْنِنِى بِفَضْلِكَ عَمَّنْ سِوَاكَ
Allahumma’kfni bi halaalika `an haraamika wa aghnini bi fadlika `amman siwaak
O Allah, suffice me with Your legitimate (provision) not from Your illegitimate and bestow me with wealth such that I shall be in need of no one other than You.
When the Rasul of Allah (saw) taught this prayer he said:
“Even if one was in as much debt as a mountain, on continual recitation of this prayer, Allah will enable him to pay his debt off…”
Those who are in debt and are having difficulty paying it are advised to read this prayer 300 times a day.
أَللَّهُمَّ رَحْمَتَكَ أَرْجُو فَلَا تَكِلْنِى اِلَى نَفْسِى طَرْفَةَ عَيْنٍ وَأَصْلِحْ لِى شَأْنِى كُلَّهُ لآَ اِلٰهَ اِلَّا أَنْتَ
Allahumma rahmataka arjoo falaa takilni ilaa nafsi tarfat `aynin wa aslih-lee sha`nee kullahu la ilaha illa anta 
O Allah, I seek Your grace, do not leave me to my self not even for a blink of an eye, correct me every instance, there is no god, only You.
The Rasul of Allah (saw) says “those who are in hardship and necessity should read this prayer” at least forty times a day.
