ISIS recruiters are praying for a Donald Trump victory come November because they believe it will help draw more jihadis to their cause, it has been reported.

Analysis of known ISIS channels on anonymous messaging app Telegram reveals that Trump is the preferred presidential candidate for extremists, Foreign Affairs magazine reports.

That is despite the fact that Trump has made his hardline stance against ISIS a keystone of his campaign while blaming Clinton and Obama's 'failed' policies for creating the group.

Writing in a recruitment thread on the app, one ISIS member said: 'I ask Allah to deliver America to Trump.'

Another added: 'The "facilitation" of Trump’s arrival in the White House must be a priority for jihadists at any cost!'

In total, the magazine spoke to 12 known members of the terrorist group, and found that Trump is by far the preferred candidate.

Interviewed about their reasons for supporting the Republican candidate, the jihadis gave three explanations.

Firstly, they believe that Trump's inflammatory rhetoric - including 'taking out' the families of fighters and 'bombing the s***' out of Syria - plays into their vision of a world in which Islam is at war with the West.

Central to ISIS philosophy is the belief - based on scripture - that the armies of Islam and the West will clash in a 'final battle' near the city of Dabiq, in northern Syria.

After this apocalyptic event they believe the West will be crushed, opening the door for a worldwide Islamic caliphate and a new age of dominance for extremists.

The vision of such a showdown is a powerful recruitment tool, one which they foresee coming true under Trump's leadership.

Second, the recruiters believe that proposals such as forcing Muslims to register on a database and increased surveillance of mosques will make it easier to radicalize people and help with recruitment.

Thirdly, fighters believe that Trump will be an unstable and irrational leader who will be easily provoked and whose decision-making will weaken the US.

Despite Clinton's interventionist stance toward the Middle East and her support for the Iraq war, recruiters say she is much harder to use in propaganda because of her tempered rhetoric when it comes to Islam.

Among Trump's more sensationalist promises is the continuation of waterboarding and 'much worse' interrogation tactics, detaining extremists in Guantanamo, and his now-revoked ban on Muslims coming to America.

This is not the first time that terrorists have used Trump as a recruitment tool.

Back in January, Somali group Al Shabaab used footage of Trump calling for a 'complete and total shutdown of Muslims coming to the United States' in one of its propaganda films.

In the film, Trump's speech is spliced with footage of now-deceased 'underwear bomb plot' mastermind Anwar al-Awlaki warning western Muslims that they face persecution which will include being locked in concentration camps.
