If a person insults someone and the person remains silent, thinking he is afraid, should he insult him?

The questioner : Some people, when they insult someone and the people remain silent toward them, assume they are afraid of them?

The Shaykh : He may think this, or he may think that he left it for the sake of Allah, so he feels ashamed. Therefore, you have the right to insult him with what he insulted you with; you have the right to do so. Therefore, if he insults you while you are fasting, say to him, "I am fasting," so that he knows that your intention with this silence is not fear. You have the right to insult him with what he insulted you with, but sometimes leaving off the insult and the retaliation is better, and sometimes it is worse if this man is known for evil and that if he insults me and I remain silent, he will insult the second and third person, or insult me again; there is no harm in that.
