When someone says anything towards you that pushes you to hold a grudge against them, have any type of ill feelings, just make du`aa’ for them. Ask Allaah to forgive them and bless them in this dunya and the aakhirah. Try to look at the good qualities of the person as well. It’s amazing how much better our lives become for doing this.
