In media appearances, Abdulmohsen has been an ex-Muslim critic of Islam. In 2019 Abdulmohsen gave interviews to the
Frankfurter Rundschau and the
Frankfurter Allgemeine Zeitung, in which he was presented as an escape/migration helper. In these he says about himself: "
I am the most aggressive critic of Islam in history. [...] There is no good Islam."
Der Spiegel reported on him in the same year; that he would - through his web forum
wearesaudis.net and
X (formerly known as Twitter) - help others to escape from Saudi Arabia to Germany. Also in the same year, Abuldmohsen appeared on the
BBC showcasing his website intended to help asylum seeking
apostates,
"especially from Saudi Arabia and the Gulf region".
On X, Abdulmohsen posted a machine gun with a US-flag as a profile picture and conspiracy theories such as "Germany is persecuting Saudi asylum seekers inside and outside Germany in order to destroy their lives" and "Germany wants to Islamize Europe." In a video interview that appeared on an anti-Islamic US blog eight days before the attack, Abdulmohsen spreads theories for over 45 minutes that the German state is conducting a "covert secret operation" to "hunt and destroy the lives" of Saudi ex-Muslims around the world, but at the same time Syrian jihadists are receiving asylum in Germany. Abdulmohsen also shared similar
right-wing ideologicalcontent, including content from German politician
Alice Weidel (
AfD),
Alex Jones and
Elon Musk. He also shared a video by German right-wing influencer
Naomi Seibt. In May 2024, he wrote: "
I seriously expect to die this year. The reason: I will ensure justice at any cost. And the German authorities are hindering any peaceful path to justice." A few minutes before the attack, he posted more videos. In one of them, Abdulmohsen. said: "
The police themselves are the criminals. In this case, I hold the German nation, I hold the German citizens responsible for what is in store for me."
