Adverts will promote giving during Islamic holy month of Ramadan.

Britain’s biggest Muslim charity is to pay for buses to carry adverts praising Allah to help victims of the Syrian war.

Buses in London, Birmingham, Manchester, Leicester and Bradford, which contain the UK’s largest Muslim populations, will have the words “Subhan Allah”, meaning “Glory be to God” in Arabic, emblazoned on their sides.

Islamic Relief said it hopes it will encourage people to donate generously to its cause ahead of the start of Ramadan on 7 June.

The annual month of fasting is also traditionally a time of increased donations for many of the Muslim community with many believing giving is multiplied during "the month of blessings".

The charity said it hoped the campaign will help young Muslims channel anger about the war in Syria and discrimination at home into humanitarian work – and divert them from extremism.

International aid has helped halve the number of people living in extreme poverty in the past 15 years

Imran Madden, the UK director of Islamic Relief, 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 this country.

"International aid has helped halve 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.”

This adverts will have special resonance in London after the city elected Sadiq Khan, its first ever Muslim mayor.
