knock

Driving away after knocking someone's car

Q: I have a small problem. This morning I went to do some shopping. While parking, I misjudged my turning and by mistake I scraped into the car next to me. It was a very small scrape, maybe just a touch up would fix the problem on their car. Due to my financial situation I got scared and drove away without informing the person. However I am now feeling really really guilty about it and i fear Allah's punishment with regards to it, like I am scared Allah will take away barakah from my wealth that I have left or something else will happen. What can I do to fix this situation as I was scared to wait for the person to tell him what had happened.
