The Book of Prayers (Kitab Al-Salat)
Muslim :: Book 4 : Hadith 2029
'Amra daughter of 'Abd al Rahman narrated that she heard (from) 'A'isha and made a mention to her about 'Abdullah b. 'Umar as saying: 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 (may peace be upon him) 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.
