ANSWER:

If you have forgiven them, this is transgressing after forgiveness 

You should move on and leave them to Allah.

QUESTION: Sheikh, some people wronged me. I’ve forgiven them. But some have tormented me so much that even after forgiving, I make dua to Allah so that HE does justice to me & decrees whatever punishment upon them HE thinks necessary. Is this kind of feeling appropriate or should I forgive & try to forget everything, thinking that Allah will satisfy me with rewards in the hereafter?
