Tanveer Ahmed, a 32 year old Sunni Muslim man from Bradford, has been jailed for life after he admitted a religiously-motivated murder of Glasgow shopkeeper Asad Shah, whom he claimed had 'disrespected' Islam.
He had stabbed 40-year-old Shah outside his store in Shawlands on 24 March because he had allegedly posted videos online in which he apparently claimed to be a prophet.
Ahmed would serve a minimum of 27 years in prison.
Mr Shah was an Ahmadi Muslim, a minority sect which is not recognised by all Muslims. The family moved to Scotland from Pakistan in the 1990s to escape persecution over their beliefs.
Jailing him for life at the High Court in Glasgow court, according to BBC, judge Lady Rae told Ahmed: "This was a barbaric, premeditated and wholly unjustified killing of a much loved man who was a pillar of the local community.
"He was described as a peaceful and peace-loving man and family man who went out of his way to show respect for those of any faith."
The judge branded the attack as "an appalling display of merciless violence".
Lady Rae added: "No-one in any civilised country including Scotland has the right to take the life of another whatever offence that individual perceives that he or she has suffered.
"It is vitally important in modern society that respect and tolerance for others of any race, creed, colour, ethnic origin or religious belief is maintained and protected by the law of the land.
"I note with considerable concern that you have expressed no remorse whatsoever for this appalling crime."
On the day of the murder, as Ahmed travelled to Glasgow, he watched a clip featuring Mr Shah on his mobile phone and was heard in a phone message to say "listen to this guy, something needs to be done, it needs nipped in the bud".
When he arrived at the shop, Ahmed said he warned Mr Shah that he was there to kill him and asked him to stop claiming to be a prophet.
CCTV footage of the attack showed Ahmed pulling a knife out and moving behind the counter and stabbing Mr Shah repeatedly.
The shopkeeper managed to get outside, but was stabbed again and then stamped on and kicked in a frenzied attack as he lay dying in the street.
Athar Shah, Mr Shah's brother tried to intervene, but was unable to fend off Ahmed, who then walked calmly to a bus shelter, as Asad lay dying on the ground. The police found Ahmed at the bus shelter, a short time later. After being arrested, Ahmed released a statement through his lawyer saying he had killed Mr Shah as he had falsely claimed to be a prophet.
No members of Mr Shah's family were in court to hear the sentence imposed, but friends were believed to be in the public gallery.
A victim impact statement written by Mr Shah's sister Attia on behalf of Mr Shah's family said Mr Shah's widow has been "brutally deprived of a life and companionship with her soul-mate and kindred spirit, the love of her life".
