Wahab refused to give evidence in court but comments he made to officers suggested the attack was committed out of revenge.
Detective Constable Sam Higginson said: This was a brutal attack on a man in a shop in the middle of the day.
The man suffered serious head injuries including a bleed to the brain and had metal plates fitted in his skull. He was in hospital for more than a month.
Wahab then fled the country in a desperate bid to escape justice. Fortunately we arrested him on his return to the UK.
