On January 17, 2020, a video was uploaded to the Internet of an event at the Al-Aqsa Mosque in Jerusalem on the anniversary of the 1453 AD capture of Constantinople by the Ottoman Empire. The event was held by Hizb ut-Tahrir. Palestinian preacher Nidhal “Abu Ibrahim” Siam spoke before the crowd and said that the anniversary of the fall of Constantinople brings tidings that Rome will be conquered in the near future. He said that three prophecies will soon be fulfilled, and he expressed hope that his audience will be the ones to fulfil them. Siam elaborated that these prophecies are the prophecy that a rightly-guided Caliphate will be established, the prophecy that Jerusalem will be liberated and established as the capital of the Caliphate, and the prophecy that Islam “will throw its neighbors to the ground” and that its reach will span across the world. He told the crowd that their real task is to wage Jihad for the sake of Allah and to make the word of the infidels inferior to the word of Allah. In addition, he called on them to seek martyrdom for Allah. He added: “Do not obey the followers of Satan [and] those who collaborate with America, Russia, and the West.” The crowd chanted: “This Al-Aqsa [Mosque] will be liberated… The Caliphate was promised by Allah… By means of Caliphate and the consolidation of power, your conquest, oh Rome, is a matter of certainty… Allah Akbar!” For more about Nidhal Siam, see MEMRI TV Clips No. 7516 and No. 7216.
