Is it permissible to speak during the Friday sermon in response to a question or in reply to a greeting?

Question : And does he speak in response to a question or in reply to a greeting?

Answer : The answer is no, he does not reply to the greeting. However, when the sermon ends, he tells the one who greeted him: “It is not permissible for you to greet, and it is not permissible for anyone else to reply to your greeting, so that he is not accused of arrogance, and so that the ruling is understood.” If he informs him of this, he gains two benefits: the first benefit is for himself, and the second benefit is for the one who did not reply. The benefit for the one who did not reply is that he avoids the accusation of arrogance, and the benefit for the one who did not greet is that he learns the ruling so that he does not do it a second time and greet.
