April 13, 2020 Extremists

Born: 1984;

Place of Birth: Diyabakir, Turkey;

Gender: Male;

Nationality: Turkish;

General Info:
Halis Bayancuk (also known as Abu Hanzala) is a member of the Zaza ethnic group born in Diyarbakir, Turkey. He had been arrested in 2008, 2011, 2014, 2015, and 2017 in police raids connected to Al-Qaeda and the Islamic State (ISIS) terrorist groups, as well as in a raid connected to the 2003 truck bombings of the Bet Israel and Neve Shalom synagogues in Istanbul that killed 23 people.

Though he was imprisoned for about five and a half out of the last 10 years, Bayancuk’s June 2018 sentence is the longest he has received. Turkish media, including state-run media, consistently describe Bayancuk as the leader of the Islamic State (ISIS) in Turkey.

In December 2014, a video surfaced in which Bayancuk said: “The Islamic State (ISIS) is our brother in faith. We count every attack against them as against ourselves. I believe that this war is a war of creed. I am with my brothers. I consider whoever does an attack against our brothers, to have done this attack against me. For this reason each of us must make our side on this issue clear.”

Terror Activities:
In May 2017, the Sakarya attorney general’s office accused Bayancuk of operating a secret mosque to recruit members for the Islamic State. A May 2018 indictment following an investigation in Diyarbakir stated that Bayancuk had said in his religious lectures that jihad is a religious obligation for all Muslims and that those who do not wage jihad are idolators.

To those who wished to make jihad, he reportedly said: “Let’s send you on jihad, we’ll cover all the expenses.” Levent Uysal, who was sentenced to life in prison for his involvement in planning the June 2016 attack that killed 46 people and wounded 163 at Istanbul’s Ataturk Airport, was found with audio and video recordings of Bayancuk’s lectures on his phone.

Uysal said of Bayancuk: “Like my other teachers, Ebu Hanzala is one who gives Islamic knowledge. I listen to Ebu Hanzala to learn Islam.” According to Bayancuk’s personal Twitter account, he is being held in the Silivri Closed Prison No. 9, located outside of Istanbul.

Promoting Salafi-jihadi ideology:
Bayancuk’s writings and videos are shared and promoted on many Turkish-language Salafi-jihadi websites and social media accounts, but the content is first uploaded to two websites with which Bayancuk is personally associated.

One,, hosts over 2,000 videos and audio recordings of his lectures, while the other,, hosts his writings and those of 35 other writers who appear to share his Salafi-jihadi views, along with a monthly Salafi-jihadi magazine called Tevhid (“Monotheism”). Aside from their focus on Bayancuk’s lectures and writing, the two websites also link to the same social media accounts, have the same “About Us” page, promote the same books, and share a similar appearance and writing style.

Many videos on discuss jihad, and offers books such as The Method Of The People Of The Sunnah And The Fundamentals Of Jihad, and Scenes From The Jihad Of The Prophet’s Companions for sale and in PDF. Almost every issue of Tevhid magazine mentions jihad, while well over half of the issues have full articles on the subject.

Though the administrators of this collection of websites and social media accounts do not refer to themselves as such, they can be thought of as parts of a single organization and therefore will be referred to in this report as the Tevhid Organization.

The Tevhid Organization has at least five websites: and, which are mentioned above;, which hosts the Internet radio station Radyo Tevhid (“Monotheism Radio”); or Tevhid Siparis (“Monotheism Order”), which is an online bookstore offering hundreds of books as well as print copies of Tevhid magazine for sale; and a fifth website,, describing Bayancuk’s life and trial. Four of these five websites are hosted in Michigan, U.S., while the fifth,, is hosted in Turkey.

Many of these accounts and pages include the Tevhid Organization’s original material translated into other languages.

On October 4, 2018, Turkish counter-terror police raided the Tevhid Organization’s Ankara office., the homepage of “Tevhid Dersleri (Monotheism Lessons),” hosts at least 2,252 videos, almost all of which are lectures, commentary, interviews, and Q&A by Bayancuk, and most of which are about 40 minutes long, though they range from two minutes to well over an hour. There are also videos in Turkish on learning Arabic, street interviews, and a nasheed (“Islamic song”).

The videos cover many subjects from a Salafi-jihadi standpoint, and are divided into categories, including: “Creed Lessons,” “Commentary Lessons,” “Islamic Jurisprudence Lessons,” “Hadith Commentary,” “Moral Lessons,” and “Method Lessons.” The page has an “Other Languages” section that includes pages for content in the English, Albanian, Georgian, Russian, German, French, Dutch, Arabic, Farsi, Kurdish, and Uzbek languages, though some of these pages are empty.
