An Islamic undertaker from western Sydney has made a bizarre video warning Muslims about the evils of celebrating New Year's Eve - as he wheeled a dead body into a fridge.

Ahmad Hraichie, a funeral director with the Lebanese Muslim Association, spent the last day of 2017 ranting against Muslims who disobeyed their faith by drinking alcohol or having sex outside of marriage.

'This is where we are all going to spend to spend our New Year's party if we die on New Year's Eve – in a fridge, in a fridge where the brothers and sisters have now have probably got their drinks all in the fridges and their snacks,' he said.

'We're going to put our brother in the fridge.

'That could have been me. That could have been you. That could have been anybody. I say this with my heart: this brother was alive now he's not.

'I could be next, you could be next.'

Attending to a dead body in a funeral parlour near Sydney's Rookwood Cemetery, Mr Hraichie railed against Muslims who had sex outside of marriage with another Muslim.

'Beware of what youse do tonight. Anyone who's going to do anything that goes against our religion of Islam – drinking, fornication, Zina – look at this man and this is an example Allah has given us.

'Stop it. Stop it before it's too late.'

He also called on Muslims to avoid celebrating New Year's Eve with non-believers who drank alcohol.

'Any other day is alright but not tonight because tonight we know what goes on.'

Mr Hraichie told Daily Mail Australia he made the video to remind Muslim youths to 'uphold their faith' and enjoy the fireworks away from the party temptations.

'Like all true Christians or Jews who abstain from sex before marriage and drinking alcohol, it's a reminder to stay steadfast in life and honest and true no matter what religion you are,' he said on Wednesday.

'My point is to our youth who lose their ways when they go all crazy partying.

'What begins with one drink ends up with drink driving and all other problems.'

He slammed the Muslim fundamentalist Ahlus Sunnah Wal Jamaah Association, which has called for Muslims to avoid non-Muslim activities altogether, adding he had no problem with Christmas decorations or New Year's Eve fireworks.

'They are extreme and there is no place for extremist clowns in Australians society,' he said. 'Everyone is entitled to worship what they want.

'I actually enjoy seeing houses decorated and the holiday season.

'Nothing wrong with fireworks. I actually watched them from the TV. Best view.'

In November, Mr Hraichie filmed a message of forgiveness from the father of a nine-old- boy, who was killed when a four-wheel drive crashed into his classroom at Greenacre, in Sydney's west.

Mr Hraichie drove the hearse carrying the body of Jihad Darwiche - one of two boys who was killed when a Toyota Kluger was accidentally accelerated at Banksia Road Primary School in Greenacre.

During the trip in the hearse, he videoed a conversation with Jihad's grieving father, Raed, agreeing that forgiveness was 'the way a proper Muslim acts in a time of calamity and tribulation'.

Mr Hraichie's estranged 20-year-old son Bourhan, an Islamic State sympathiser, clearly didn't get the message, as he serves time inside Goulburn Supermax, Australia's highest-security prison.

During his initial sentence at Kempsey prison, Bourhan was charged with carving the Islamic State slogan 'e4e', or 'an eye for an eye', into a fellow inmate's forehead in April 2016.

Bourhan also threatened to behead New South Wales prisons boss Peter Severin.

During his career Ahmad Hraichie has buried underworld figures.

He grew up in Penshurst, in Sydney's south, alongside many men who eventually turned to a life of crime, including ex-Comanchero bikie boss Mick Hawi.
