"Taken too soon, Sam was a man full of life, he was loved by all and his smile would always light up the room," his funeral notice read.
"A loving father, son, brother, uncle, nephew, cousin, partner and friend. He will be dearly missed, but never forgotten."
Following the service, the coffin was draped in a green cloth and placed in a hearse to be driven to Northern Memorial Park for burial.
The road near the service was closed for a procession led by a portrait of Abdulrahim, followed by motorbikes, four men carrying flower arrangements that spelt out the nickname "Suna", Â and the hearse.
Police were parked across the road, keeping watch.

Homicide detectives are trying to find Abdulrahim's killers and are examining two burnt-out cars.
A Porsche SUV was found burnt out at Reservoir an hour after the shooting.
A grey Ford Ranger with a distinctive sticker of bull horns on the ute's canopy rear window was found at Westmeadows and was also set ablaze, police confirmed on Wednesday.
Abdulrahim was shot in 2022, attacked with a rock in prison in 2019, shot at again in 2024 and was put back in prison at one point because police feared he was the target of three shooting incidents.
The attempts started from the belief he was connected to the killing of another gangland figure in 2016.
