Billboards attacking ISIS are appearing across major US cities, declaring 'Hey ISIS, you suck!' and signed by 'Actual Muslims'.

Dubbed Islam's 'declaration of independence' from ISIS, the advertising has been sighted along roads in Chicago and Phoenix after being erected by a Chicago-based Islamic public relations company, Sound Vision Foundation.

The billboard says 'Life is sacred' and references verse 5:32 of the Koran, which warns against killing.

The billboards are signed 'From: #ActualMuslims'.

Muslim groups in up to 15 other cities were now requesting for signs to be installed in their area, RT reported.

The foundation's Imam Abdul Malik Mujahid told CBS News Chicago that attacks in Europe and the US caused his group to become more pro-active.

'Our neighbors don't realize that Muslims are absolutely opposed to ISIS,' he said. 'ISIS actually kills more Muslims than anyone else.'

KORAN, VERSE 5:32 'Because of that, We decreed upon the Children of Israel that whoever kills a soul unless for a soul or for corruption [done] in the land - it is as if he had slain mankind entirely. And whoever saves one - it is as if he had saved mankind entirely. And our messengers had certainly come to them with clear proofs. Then indeed many of them, [even] after that, throughout the land, were transgressors.' Advertisement

Sound Vision Executive Director Mohammad Siddiqi told CBS Phoenix: 'This is our declaration of independence against ISIS. It's as simple as that.'

Retired professor and follower of Islam Dr Aneesah Nadir told Fox10 Muslims were often the target of bullying and physical violence because the religion's extremist element.

'We want our neighbors to know - we're colleagues and classmates and neighbors, and we want our neighbors to know that we don't approve of this at all,' Nadir said.

'In fact, Prophet Mohammed, peace be upon him taught the exact opposite of what ISIS is portraying and we want everybody to know that.'
