In the video, which is not online but has been seen by The Sun, he says: 'There is no solution to the Syrian situation while Assad is in power… if you want to help then shine a light on the atrocities carried out by Bashar Assad, the Russians and ISIS.'
'It is very unfair for the West to judge Muslims by the actions of Al Qaeda, ISIS or Hizbollah. If that is fair then all Muslims have the right to view all Christians as crusaders or Americans as Charles Manson.'
He adds: 'I will continue to stand by the side of the Syrian people and fight for their causes that many loved ones have sacrificed their lives for.'
Mustafa's father, Hamza, rose to notoriety in the UK after becoming imam of the Finsbury Park mosque, in north London, in 1997
Since making the 22,000-mile journey to Syria, Mustafa has played an active role in fighting and was involved in the siege of Aleppo, intelligence insiders claim.
It is unclear which rebel group Mustafa is fighting for.
Mustafa is the sixth of eight children fathered by Hamza, 58, an Egyptian-born hate preacher who is now serving a life sentence in a US prison for terror offences.
An intelligence insider told The Sunday People that Mustafa has no criminal record in the UK, but he 'has been part of military operations' in Syria.
The insider added: 'He has managed to stay a ghost since he set foot in Syria but it's thought he has been with rebels in the north.'
Experts believe that more than 800 Brits have flocked to Iraq and Syria to join 27,000 foreigners fighting for IS since violence broke out in 2011.
Mustafa's father, Hamza was jailed for life for terrorism offences during a trial in New York City in 2015, and has been serving his sentence in solitary confinement at a high security prison in Florence, Colorado.
Hamza was extradited to the US after the British government spent a decade trying to kick him out of the country.
He rose to notoriety in the UK after becoming imam of the Finsbury Park mosque, in north London, in 1997.

One year later, in 1998, he helped organise hostage-taking of 16 mostly British tourists in Yemen. Three Britons and an Australian killed in rescue mission.
In 2000, he set up a terrorist training camp back in the US, in Bly, Oregon, sending volunteers and money to Afghanistan to support al Qaeda and the Taliban.
He then firmly placed himself on the national radar in 2001 after speaking out in support of Osama bin Laden following the September 11 attacks.
His current jail is known as the 'Alcatraz of the Rockies', due to its reputation as being inescapable.
It houses the most dangerous inmates in the US prison system and is believed to the world's most secure prison.
Two of Hamza's sons, as well as a stepson, have also been jailed for various offenses, including a bomb plot and a robbery.
