Attending the funeral of non-muslims

Im sorry for neglecting my blog for so long. I didn't have the possibility to write for a while. I hope from now on i will be able to post more often on my blog. Todays topic inspiration: Someone asked me - Is it permissable for a Muslim to atend a non Muslim burial or visit the family of the deseased ? Specially converts are often confronted with the situation and often insecure whether to attend the funeral of a non-muslim relativ, or not. Here is the fatwa i found.... 

Attending a non-Muslim neighbor's funeral:
According to one hadith of the Prophet (SallAllâhu ‘Alaihi Wasallam) related by Tabarani regarding the rights of neighbors it says: "The rights of the neighbor is that, when he is sick you visit him;
when he dies, you go to his funeral;........" Since this hadith is talking about neighbors and
the neighbor can be a non-muslim, so is it permissible for the Muslim to attend a non-Muslim's funeral?

* Please shed light on this issue in accordance with the Qur'an and the Hadith. * Also this issue is very important for the new Muslims whose parents have not accepted Islam. Is it permissible to attend a funeral for the non-Muslim parents?

It is permissible for a Muslim to attend a kaafir’s funeral if the kaafir is a relative, such as a mother, father, brother or other relative, but it is not permissible to join in the prayers or any other rites of their religion.

Zakariya al-Ansaari (RadhiAllahu 'Anhu) said:
“He may (i.e., it is allowed for the Muslim and is not makrooh) attend the funeral of a kaafir relative, because of the report narrated by Abu Dawood from ‘Ali who said, ‘When Abu Talib died, I came to the Messenger of Allah (SallAllâhu ‘Alaihi Wasallam) and said, ‘Your uncle, the misguided old man, has died.’ He said, ‘Go and bury him.’”
(Reported by al-Nisaa'i, 190).

Al-Adhraa’i said: “It is possible that this includes permission to attend the funeral of a wife or slave…”

Hadith on Death (Funeral):

The Prophet (SallAllâhu ‘Alaihi Wasallam)  stood up for the funeral of a Jew out of respect for his humanity Ibn Abu Laila reported: Sahl ibn Hunaif and Qais ibn Sa’d ibn Ubaidah were in 
Al-Qadisiyyah when a funeral passed by them, so they stood up and it was said to them, “It is one of the local people.” They both said: A funeral passed by the Messenger of Allah (SallAllâhu ‘Alaihi Wasallam) , and he stood up. It was said to him, “It is a Jew.” So the Prophet said, “Was he not a soul?”
