CHRISTIANS in Sydney will have their core beliefs challenged by provocative advertisements due to appear on billboards and buses in the next month.

The ads, paid for by an Islamic group called MyPeace, will carry slogans such as ''Jesus: a prophet of Islam'', ''Holy Quran: the final testament'' and ''Muhammad: mercy to mankind''.

Thought-provoking? Yes it is ... an advertisment paid for by Islamic group MyPeace.

A phone number urges people to call to receive a free Koran and other Islamic literature.

The organiser of MyPeace, Diaa Mohamed, said the campaign was intended to educate non-Muslims about Islam. He said Jesus was a prophet of Islam, who was to come before Muhammad. ''The only difference is we say he was a prophet of God, and they say he is God,'' Mr Mohamed said. ''Is it thought-provoking? Yes, it is. We want to raise awareness that Islam believes in Jesus Christ,'' he said.
