What did the Prophet Muhammad (saw) say regarding the punishment a dead person might experience if his family laments for Him?
 'Abdullah b. Abu Mulaika reported:                      I was sitting by the side of Ibn 'Umar, and we were waiting for the bier of Umm Aban, daughter of 'Uthman, and there was also 'Amr b. 'Uthman. In the meanwhile there came Ibn 'Abbas led by a guide. I conceive that he was informed of the place of Ibn 'Umar. So he came till he sat by my side. While I was between them (Ibn 'Abbas and Ibn 'Umar) there came the noise (of wailing) from the house. Upon this Ibn 'Umar said (that is, he pointed out to 'Amr that he should stand and forbid them, for): I heard the Messenger of Allah (may peace be upon him) as saying: The dead is punished because of the lamentation of his family. 'Abdullah made it general (what was said for a particular occasion). Ibn 'Abbas said: When we were with the Commander of the believers, 'Umar b. Khattab, we reached Baida', and there was a man under the shadow of the tree. He said to me: Go and inform me who is that person. So I went and (found) that he was Suhaib. I returned to him and said: You commanded me to find out for you who that was, and he is Suhaib. He (Hadrat 'Umar) said: Command him to see us. I said: He has family along with him. He said: (That is of no account) even if he has family along with him. So he (the narrator) told him to see (the Commander of the believers and his party). When we came (to Medina), it was before long that the Commander of the believers was wounded, and Suhaib came weeping and crying: Alas for the brother, alas for the companion. Upon this 'Umar said: Didn't you know, or didn't you hear, that the Messenger of Allah (may peace be upon him) said:" The dead is punished because of the lamentation of his family"? Then 'Abdullah made it general and 'Umar told it of certain occasions. So I ('Abdullah b. Abu Mulaika) stood up and went to 'A'isha and told her what Ibn 'Umar had said. Upon this she said: I swear by Allah that Allah's Messenger (may peace be upon him) never said that dead would be punished because of his family's lamenting (for him). What he said was that Allah would increase the punishment of the unbeliever because of his family's lamenting for him. Verily it is Allah Who has caused laughter and weeping. No bearer of a burden will bear another's burden. Ibn Abu Mulaika said that al-Qasim b. Muhammad said that when the words of 'Umar and Ibn 'Umar were conveyed to 'A'isha, she said: You have narrated it to me from those who are neither liar nor those suspected of lying but (sometimes) hearing misleads.
