The father of Sydney schoolboy Jihad Darwiche, who was killed when a car smashed into his classroom this week, has sent a message of support to the driver.
The father of a young boy killed when a car smashed into his Sydney classroom has forgiven the driver in an extraordinary speech videoed in the hearse as it carried his eight-year-old's coffin to the cemetery.
Jihad Darwiche's funeral on Thursday came two days after he and a friend, also eight, were killed when an out-of-control SUV smashed into their classroom at Banksia Road Primary School in Greenacre.
A dashcam video from the hearse shows Jihad's father speaking in Arabic while his son's green casket - draped in a black and gold cloth - lies in the rear of the vehicle.
The driver of the car, family friend Ahmad Hraichie, translates for Jihad's father in the video broadcast via Facebook.
"Allah has called for his boy, he (the father) is very happy," Mr Hraichie says.
"The father says all the threats to this lady, the abuse, is not from them.
"No retaliation is coming from the family of the boy. They have forgiven - if anything they want to sit with this lady and tell her we forgive you."
Jihad's father says his family hopes to extend a hand to the woman.
"When all of this is over she is welcome to come and sit with the family, have a meal and talk about how they can move forward."
Earlier, the boy's casket was carried by a dozen pallbearers down the steps of the Lakemba Mosque as mourners spilled onto the street.
Many were in tears as it was loaded into the white hearse for the short drive - captured on video - to a nearby cemetery. The hearse was accompanied by a police escort.
Mr Hraichie told AAP that Jihad's death had hit him "close to his heart". He applauded the father's strength.
"I can only hope to be half the man he is."
The two eight-year-old boys were killed on Tuesday when an SUV driven by 52-year-old mother Maha Al-Shennag crashed into a classroom housing 24 students.
NSW Police on Thursday said Al-Shennag had been additionally charged with dangerous driving occasioning grievous bodily harm and causing actual bodily harm by misconduct.
She was initially charged on Tuesday with two counts of dangerous driving occasioning death and negligent driving occasioning death after the crash at the school.
Seventeen children and one female teacher were treated at the scene by NSW Ambulance paramedics.
Two eight-year-old girls and a nine-year-old girl were taken to hospital on Tuesday with two of them released on Wednesday afternoon.
Banksia Road Primary School has reopened with specialist counsellors and additional teaching staff from nearby schools.
A makeshift memorial outside the school gates has been growing, with students, parents and teachers leaving flowers, tributes and balloons.
Al-Shennag, whose licence was suspended on Tuesday, has been granted conditional bail and is scheduled to appear at Bankstown Local Court on November 29.
