Sajid Aslam is also pleading for the release of his wife.
Lorna Moore, 33, was convicted in February of concealing information that her husband was joining ISIS.
Mr Aslam sent an email and Star in Birmingham in which he claimed that he is not fighting for the evil terror group in Syria.
He claims instead that he is volunteering as a teacher at a makeshift school for child refugees in Turkey.
Mr Aslam even included a picture of himself playing video game Call of Duty.
He said: “This is the nearest I’ve come to firing a gun.”
Mr Aslam also pleaded for an opportunity to prove his and his wife’s innocence.
He said: “I hope my message reaching the public domain would pressure the authorities to respond to my attempts to contact them, and that I would be given the opportunity to return to Britain to prove my innocence and my wife’s innocence – reversing the terrible suspicions, accusations, and terrible miscarriages of justice which have been inflicted upon us.”
Ms Moore is facing several years in jail after being found guilty of failing to disclose information about her husband’s planned travel.
A court heard that Moore took her children to Skegness after Mr Aslam fled the UK.
She later told counter-terrorism police that she assumed he had gone on holiday by himself.
But three months later she booked flight tickets to join her husband in Syria, the Old Bailey heard in the three-week trial, Express reported.
