Hot on the heels of their recently shocking handbook on how to treat their female sex slaves, The Islamic State has recently launched a guide for mothers on how to raise "jihadi" babies.

The guide titled “Sister’s Role in Jihad” says the most important role a woman can play "off the battlefield" in jihad is believe it or not - raising mujaheddin children.

The Islamic State clearly believes it is better to start young, priming their children for a life of violence and to kill people in the “name of God."

“Don't wait until they are seven to start, for it may be too late by then!” the handbook reads. It also recommends showing children jihadi websites, reading bedtime tales of jihad, and encourages sports such as darts to improve their aim and push ups to increase their stamina.

Encouraging their children to play with toy guns, the Islamic State guidebook however cautions the mothers to make sure their children "only take their anger out on the enemies of Allah who fight against Muslims".

This recent addition to their cookbooks and female sex slave guides has been shared online by all IS social media accounts, and was brought to attention by the monitoring group Memri on their report on how children are being indoctrinated into radical Islam.

Steven Stalinsky, executive director of Memri, in an interview with the Daily Mail said that 2015 was expected to see a significant surge in “effort to indoctrinate the next generation of fighters”.

He said: “'No matter what happens in Iraq and Syria in the near future, the next generation – the children of Baghdadi and grandchildren of bin Laden - have already been brainwashed to hate the West and to strive for jihad and martyrdom.”

Shockingly, the mothers are also instructed to remove all western influences like television to "protect little ears as it mostly teaches shamelessness, anarchy, and random violence". But in a compromise it declares that if the mothers "cannot eliminate the television completely, then at least use it only to show children videos that will instill in them the love of Allah, the love of Islam, the love of the Mujahideen, and the love of Jihad."

They go on to insist that many Islamic videos as well as military training videos are available from various sources.

The original authors of the textbook are unknown, as it is usually posted on file-sharing site anonymously, but it is thought to be used by ISIS and other terror groups. You can read the full text here.
