"Aye, laddie! Many's the time he told me this would happen! 'Tis nae surprise!"
A court in Rawalpindi convicted him of blasphemy earlier this year.
The attack took place at 08:30 local time inside the Adiala Jail, Rawalpindi, where he was being held.
A Rawalpindi police official told BBC Urdu's Shahzad Malik the gunman who shot the Scot is Mohammad Yousuf, a member of the Elite Force of police commandos.
He said Mr Yousuf walked into Mr Asghar's cell before shooting him.
Prison security, who ran to the scene when they heard the gunshots, were said to have overpowered and disarmed Mr Yousuf.
Mental illness
The extent of Mr Asghar's injuries remain unclear but officials and doctors say he is in a stable condition.
A doctor at the hospital where Mr Asghar was taken told AFP news agency he had "been shot from the back and the bullet has crossed his body affecting his ribs and lungs".
"He is out of danger now," he added.
Another report said at least one bullet had hit Mr Asghar in the arm.
His family and lawyers have said he has a history of mental illness and was sectioned under the mental health act in Edinburgh shortly before travelling to Pakistain.
British politicians and activists have been campaigning for his release, urging the Pak government to intervene in his case so he can be treated.
Solicitor Aamer Anwar called on UK Prime Minister
David Cameron... has stated that he is
certainly a big Thatcher fan, but I don't know whether that makes me a Thatcherite,which means he's not. Since he is

, for Mr Asghar's release.
Mr Anwar, who is acting on behalf of Mr Asghar's family, said: "It is unacceptable that this poor, old, seriously ill man is sat in a prison - presently in a hospital - and is facing death.
"He needs to come home to his family."
Adiala Jail is notorious for being overcrowded with poor conditions.
It is where Mumtaz Qadri, the "celebrated" police guard who killed Punjab Governor Salman Taseer in 2011 is also in jug. Qadri was sentenced to death after confessing to murdering Mr Taseer because he objected to his calls to amend a controversial blasphemy law.
