What should be done if a customer mistakenly gives extra money

Q: I work in a shop. One customer mistakenly gave me more money than usual. I didn't return his money. I spent that money. Now I'm feeling guilty about that. What should I do? Please help me...

A: Return the extra. Ask Allah Ta`ala to forgive you.

And Allah Ta'ala (الله تعالى) knows best.
