Dale Jones, aged 30, of East Bawtry Road, Rotherham, savagely attacked Mr Ahmed, aged 81, while he was on his way to mosque on August 10 last year.
There was no reaction from Jones as the unanimous guilty verdict was read out.
Gasps and cries of ‘Yes!’ were heard from the public gallery as the verdict came in at Sheffield Crown Court.
The jury is still deliberating its verdict on co-defendant Damien Hunt, who is also accused of murder.
Hunt, aged 30, of Doncaster Road, East Dene, denies the charge and has previously told the court that Jones was solely responsible for the horrifying attack.
The court has previously heard the pensioner quietly ignored taunts that he was ‘out grooming’ while on the way to mosque.
Jones had consumed a cocktail of booze and drugs before he inflicted his sustained attack on Mr Ahmed and had got himself into a ‘raging fury’ following several hours of drinking and drug-taking.
Andrew Robertson QC, prosecuting, previously said Jones had already made threats to kill his girlfriend’s former partner that night and had tried to attack an Asian taxi driver while shouting racist abuse at him, moments before coming across Mr Ahmed.
The pensioner was repeatedly punched, kicked and stamped on the head in a racially-motivated murder, Mr Robertson said.
He told the jury in the trial opening: “Mr Ahmed was left lying on the grass where he had been knocked to the ground and kicked to the head. A passer-by found him two hours later at 5.25am and flagged down a police car.”
