A Sydney man who repeatedly stabbed his wife over an affair before calmly telling police he'd killed her has again been found guilty of murder.
Shahab Ahmed also confessed to a triple-zero operator, saying he had used a knife and it happened a couple of minutes ago.
The 38-year-old pleaded not guilty to murdering Khondkar Fariha Elahi, 29, in their Parramatta unit on February 18, 2017.
But a NSW Supreme Court jury on Wednesday found him guilty of the crime.
He faced a retrial after a successful appeal over the same verdict at a judge-alone trial in 2019.
Ahmed had claimed the partial defence of substantial impairment by abnormality of mind in the form of a depressive illness, offering to plead guilty to manslaughter.
Ahmed's triple-zero call was played to the jury and began with him saying: "I killed my wife" before he gave his address, name and date of birth.
He said he had used a knife and "she is in the bed".
"How long ago did it happen?" asked the operator.
"Just a couple of minutes ago," he replied.
He said she wasn't breathing and an ambulance was not needed.
Ahmed said his wife had had an affair with one of his friends a few years ago and had said it was over, but "I checked her phone today".
Acting Sergeant Michael Outzen told the jury he ran up to the flat and asked Ahmed if he called police to be told: "Yes, I killed my wife".
"He was surprisingly calm," he said.
Ahmed said his wife was in the bedroom, before the officer told him to get on the kitchen floor.
"He was very calm, very slow and concise," he said.
He could see blood on Ahmed's pants and when he went to the bedroom, saw a female lying on the mattress covered in blood.
"The woman was wearing a white dress almost completely covered in blood."
A knife was on the floor as well as a bowl containing cigarette butts.
A detective recorded Ahmed at the scene when he said he and his wife had argued.
She had had an affair with his friend Omar Khan about two years ago but told him it was over.
"We stayed separated for a couple of months and I went to my country," he said.
She told him maybe they don't have a future together because she thought her husband could not trust her anymore.
"I checked her phone and she still has a relationship with him and I killed her," Ahmed said.
In finding him guilty of murder at the first trial, Justice Monika Schmidt said the obvious ferocity of the attack was quite consistent with deliberate acts and not just a loss of control.
She described Ahmed's behaviour as "unarguably calculated" and "entirely consistent" with him ensuring Ms Elahi's life could not be saved.
The judge said Ahmed knew his wife was desperate to divorce him and had searched the internet for punishments for adultery.
Ahmed told a psychiatrist the cheating made him so angry he felt "like smoke was coming out of his body".
Justice Natalie Adams listed his sentence hearing for December 13.
