Speak positively about the deceased.

The Prophet Muhammad taught us to always speak positively of those who have passed away, even if we did not get along with them in life. We should remember that everyone has some good qualities, and it is important to focus on those when talking about someone who has died. We should also refrain from speaking badly or gossiping about them, as this will not bring any benefit and can cause hurt feelings among family members or friends. This hadith teaches us to be respectful of others even after they are gone, and reminds us that our words have power and can affect people's feelings even after death.
