Correcting the injustice carried out
Q: I wronged a disbeliever in a non-Muslim country and was thereafter fined quite a lot of money (the money went to the disbeliever). The disbeliever has not forgiven me so far. If the disbeliever dies without forgiving me, is it possible that Allah Ta’ala may not punish me in the hereafter for wronging the disbeliever by telling me that I was already punished in the worldy life (by being fined)?
A: Once you have tried your best to correct the injustice then you are absolved of the sin.
And Allah Ta’ala (الله تعالى) knows best.
