The dead is punished because of the lamentation of the living. Upon this 'A'isha said: May Allah have mercy upon the father of 'Abd al-Rahman (Ibn 'Umar). He did not tell a lie, but he forgot or made a mistake. The Messenger of Allah (ﷺ) happened to pass by a (dead) Jewess who was being lamented. Upon this he said: They weep over her and she is being punished in the grave.
Sahih Muslim Book 11, Hadith 34
