Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
How can someone forgive and pardon people who have wronged him?
We can attain praiseworthy traits and rid ourselves of blameworthy traits with a combination of knowledge and action. We should thus remember the greatness of pardoning and forgiving people and the reward for doing so. We should reflect upon examples of the forbearance of the Prophet ﷺ and the pious, love them for the sake of Allah, and then force ourselves to forgive those who have wronged us and to treat them well.
