A sermon attacking child sex grooming, which has been written by an imam who works with young people in Keighley, will be read out in 500 UK mosques today.

Alyas Karmani is due to deliver his own sermon in Bradford this afternoon.

It opens with a quotation from the Qur’an forbidding “sexual indecency, wickedness and oppression of others”, and was composed for a campaign called Together Against Grooming.

Mr Karmani has supported Keighley’s Star Youth project, which arranges workshops to steer young men away from involvement in sexual exploitation and other serious crimes.

He warned: “We come from a culture where we don’t talk about these issues, so young people end up living a double life."

He condemned disrespectful attitudes towards women, which treat them as objects instead of people, and also blamed the prevalence of pornography in society.
