financial issues

My mother is a working lady. She has helped somebody regarding the passport issues. If my mother asked her extra 1,000 from the money that was actually needed without letting her know for what she is using. Is she wrong in doing that??  she used that money not for herself but for helping the needy. Her intentions were pure�People tell her that it is her right to ask for the money to this person because it was impossible for that work to be done , but she did not do that. She is a little bit worried for her actions  

if she did wrong. what she must do now??

She should tell the person what she used the extra money for.it won�t be ok right??

Or she should just ask forgiveness from Allah ??
