Miscellaneous masaail of Janaazah

Q: If pictures of a deceased person are being displayed, who will be sinful, the deceased or the living?

Q: Me and my wife life where there is no Muslim graveyard. There is only a Christian graveyard. My wife also reverted to Islam. If me or my wife die can we be buried in the Christian graveyard if we don't have money to send the body to a Muslim country. If someone makes our funeral in a Muslim country masjid while our body is not there, will this funeral be valid while we buried in this non muslim country? 

Q: In case of a death in a family, for example the father dies, then who is responsible for fulfilling the requirements such as bringing kafan, digging the grave, making arrangements for the guests to sit and stay, and so on? Because the near ones such as the wife, sons and daughters of the deceased are in grief, so they are not in a position to make necessary arrangements.

Q: Can a person send salaams to his deceased relative at a mayyit of another deceased relative? For example, a person goes by the ear of the deceased and tells the deceived to send salaams to one of the relatives that passed away before. Do they receive the salaams?

Q: Can we write Durood on a marble slab and keep this slab at the grave so that people who come to the graveyard will read it? Is this permissible in Islam?

Q: I came across that death terminates marriage. But I have seen a hadith that our Nabi (sallallahu alaihi wasallam) said to Ayesha (radhiyallahu anha) that if she dies first then he will give her a bath. Also, Ali (radhiyallahu anhu) gave Fatima (radhiyallahu anha) a bath. Can you give me authentic ahaadith and proofs that death terminates marriage? In afterlife, will husband and wife would be together in jannah. So it is really confusing.

Q:

1- In some Kitaabs stories are mentioned of pious people getting buried next to sinful people due to the punishment on the sinful it has effected the pious in the grave and caused the pious to get old and have white hair etc, is it proven from Quran and ahadith that burying a pious person next to a sinful person will harm the pious person in any way?

2- Is it proven from Quran and ahadith that a person who has passed away feels and knows when he is bathed, shrouded etc and who is doing it?

Q: Foreign countries offer cremation and sacking of the misscarried fetus. My aunt was 5 weeks pregnant and miscarried and not well at that time chose cremation for the fetus. Is that right or not. If not what can be done to make up for it.

Q:

1. I heard that if someone has a debt and passes away then that person would never enter Jannah, is that true?

2. What if someone has debt and leaves this world, he wanted to pay for it but he didn't, would Allah still deny him Jannah?

Q: If one does not pay traffic fines and passes on, does it fall under a debt on the deceased?
