The unrepentant killer of Asad Shah says he does not care if he gets "100 years or even death" for his crime.

Religious zealot Tanveer Ahmed has admitted he murdered the Glasgow shopkeeper because he had insulted Mohammad by declaring himself a prophet online.

The 32-year-old will be sentenced next month but in a defiant call from the city's Barlinnie jail - later posted on Youtube - he insists his killing was just and that he does not fear his punishment.

Referring to Mr Shah's family as Qadiani - a derogatory term for their minority Ahmadi branch of Islam, in an Urdu-language statemennt Ahmed says that he is untouched by their pain.

He said: "I stood guard on the honour of Prophet Muhammad and I shall do it again if I shall get a chance.

"My lawyer says that there is a lot of pressure from media, local lawyers politicians and Qadiani family which is mobilizing pressure by meeting prosecutors and judges. But I am unmoved. If my God is happy with me then I don't care if I get 100 years or even death."

The High Court in Glasgow had heard that Ahmed had not killed Mr Shah because he was Ahmadi but because of the new and allegedly blasphemous beliefs. But Ahmed's actions were firmly in the context of persecution of Ahmadis and others who do not stick to mainstream Islam.

Mr Shah's family have said they are so upset by the murder that most of them are fleeing Scotland, a country they chose to be free of oppression in their native Pakistan.

It has now emerged that Ahmed was inspired by Mumtaz Qadri, the murderer of a Pakistani politician who criticised that country's blasphemy law and was executed earlier this year.

Mr Qadris brother, Diplazeer Awan, has said that he was contacted by Ahmed about Mr Shah, whose Facebook postings and Youtube videos contained claims he was a new Jesus.

Mr Awan said: "Tanveer Ahmed was very upset and he said it would be good for society if this person was sent to hell as soon as possible."

Speaking to BBC's Newsnight programme, he added: "He told me about a dream where he had seen Mumtaz Qadri and that Mumtaz Qadri sat next to him and told him he loved him.

"He said Mumtaz Qadri told him Allah had chosen him to do a noble duty for religion."

Mr Ahmed was a Sufi, traditionally seen as a spiritual and non-violent branch of Islam. So was Qadri, whose execution sparked controversy in both Ahmed's home town of Bradford and Glasgow.

Earlier this year it emerged that the main imam at Glasgow Central Mosque had praised Qadri as "a true Muslim" in a social media exchange that brought Pakistan's often bitter religious politics to Scotland.

BBC Newsnight has obtained what it said it believed to be a Facebook posting by Ahmed in jail where he suggests beheading as a punishment for blasphemers.

A former colleague, who worked with Ahmed at the same taxi firm told The Bradford Telegraph and Argus: "He was just a normal guy. I was shocked when I found out it was him.

"When I worked with him he was a big, friendly giant. He never raised his voice, he didn't look threatening.The other drivers never had a disagreement with him.

"He used to come in to work looking clean and fresh and smelling nice. He was probably the last person in the whole office you would have expected to do something like this.

"He was a decent guy. He was deeply religious, but not fanatical. He said to me on a couple of occasions: "You should pray."
