The banner adverts featuring the Arabic phrase "Subhan Allah" (Glory be to God) will now be carried by London's iconic red buses and public transport in other British cities, to encourage British Muslims to support Syrian war victims.

The posters will appear on hundreds of buses during Ramadan, which begins at sunrise on June 6 and lasts until July 7.

The ad campaign have targeted  to raise money for victims of the Syrian Civil War during the holy month of Ramadan in June, when Muslims traditionally fast and give to charity.

The start of the campaign will begin a month after London elected the first Muslim mayor of a major Western city, Labour's Sadiq Khan - who coincidentally is the son of a bus driver.

The posters are set to appear in areas with large Muslim communities, including London, Birmingham, Manchester, Leicester and Bradford.

Organizers hope that, it will present Islam in a positive way and encourage British Muslims to donate to humanitarian efforts for victims of the ongoing war in Syria.

Director Islamic Relief, Imran Madden said. "In a sense this could be called a climate change campaign because we want to change the negative climate around international aid and around the Muslim community in the country,"

"International aid has helped the number of people living in extreme poverty in the past 15 years, and British Muslims are an incredibly generous community who give over 100 million to international aid charities in Ramadan."
