How to repent of cursing a person wrongfully
I am 31 years old Muslim from Bangladesh. Back in 2003 I cursed a man because I thought he was doing some harm towards me but later I found out he was not responsible for this. I repented to Allah and I give money to the poor for that person. What else can I do so that curse will not harm me nor that person.By the way I have no contact with the person.
