What is the validity of the saying that a living person remembering a deceased person with sadness, weeping, and emotional distress harms the deceased and offends them, and that one should only supplicate and seek forgiveness for them, and what should be done regarding the deceased?

It has been reported that the deceased is tormented by the weeping of his family over him. This torment has been interpreted as the deceased's pain and sorrow over his family's actions, and not a torment of fire. This occurs if he enjoined them to do so or did not caution them against wailing and lamenting. As for merely remembering him and grieving for him, this does not fall under the prohibition.
