After publishing a biography of “Jihadi John” (AKA Abu Muharib al-Muhajir) in its English magazine “Dabiq,” the Islamic State (IS) published an alternate version in its Arabic weekly newspaper “al-Naba,” featuring new photos of the man behind the beheading of American, British, and Japanese nationals, and threatening Britain. The 15th issue of al-Naba for the Hijra year 1437 was distributed on Telegram and Twitter on January 26, 2016. The English biography of “Jihadi John” appeared in the 13th issue of Dabiq, which was released on January 19, and briefly touched upon his background, the pursuit of him by the British intelligence, his association with two fighters in the Shabaab al-Mujahideen Movement who were killed in a drone strike in Somalia four years ago. The Arabic version of the biography is missing details, such as his being a Kuwaiti national, his traveling with a companion to Syria, and his likening Nusra Front leader Abu Muhammad al-Julani to former Islamic Courts Union leader Sharif Sheikh Ahmed.

The article, “Abu Muharib al-Muhajir - A Mujahid who Preoccupied the West in Life and Death,” lauded “Jihadi John’s” beheading of captives, writing:

“Jihadi John,” as the Western media likes to call him, was known for his messages that he wrote with the blood of the disbelievers whom he slaughtered with his knife. They are such messages where heads rolled between their lines, and the pillars of the American Black House shook from their words, and the throne of Elizabeth trembled with bricks of a kingdom whose sun did not set in its colonies, and the Churches of Rome shivered from fear with the threat of their conquest and prayers being performed in them soon. Yes, the echo of the words of Abu Muharib, may Allah have mercy on him, have reached every corner of the corridors of Europe and the streets of America, and his words were heard by its deaf politicians and leaders.

Also featured in this issue is an infographic on attacks in the IS’ Sinai Province since pledging to the IS in November 2014, claiming to have killed and wounded over 1,400 Egyptian security forces, spies, and tribal militiamen; pieces on IS attacks in its provinces during the past week, with titles such as “In al-Husayba, Kilo 70, and Talat Mushayhid, the Rafidah, with their Army and Police, Lost More than 100 Killed in al-Ramadi,” “Mujahideen of Diyala Thwart a Rafidhi Attack on the Area of al-‘Adheem, and the Escalation of Jihadi Operations in Mandli,” and “Seizing Control Over Significant Positions of the Nusayri Army in Damascus Province”.

It also threatened Britain with a ”message” similar to that delivered to France with the Paris attacks:

The message that the soldiers of the Caliphate signed with their blood and sent to France in their own way is not the last. Britain, which Abu Muharib kicked and left as an immigrant towards the Islamic State, is not far from these messages. It has a share from the portion of the lion, with permission from Allah the Almighty, for it announced its war on Muslims and its hands are involved in the blood of the sons of Islam. The mail will be delivered to it, with the power of Allah, bearing a message that due to its eloquence, the hair of the young babies will turn gray.

Another article, “Soldiers of the Cross… On the Ground,” discusses U.S. Defense Secretary Ashton Carter saying that U.S. forces will be deployed on the ground to fight the IS, after coalition airstrikes and allies in Kurdish Peshmerga and YPG, and the Iraqi army were unable to stop the group. It stated:

On the other hand, the American decision is an important indication of the state of exhaustion, which the forces allied to the Americans from among the Rawafidh, the Awakenings of Iraq and Sham, and the secularist Kurds had reached after these long months of war against the Islamic State, whose army, by the grace of Allah, continues to prove its high ability to execute large military campaigns, which increases the exhaustion of the enemies and push them towards collapse. Thus, America repeats what the Russians and the Rafidha of Iran did by standing alongside their Nusayri ally [Bashar al-Assad], for his army was about to collapse, and they supported him with air coverage and thousands of infantry forces, so that he regains his balance and can finish the battle.

The deployment of American forces in Iraq or Sham will not be enough to end the battle against the Islamic State, which has expanded the battlefield very much, to extend the plans of American military intervention and include provinces of the Islamic State in Khorasan, Barqah, Tripoli, and perhaps soon in the provinces of Sinai, Aden, and West Africa. The coming months will reveal bigger surprises, Allah permitting.
