On February 25, 2022, Australian preacher Wisam Hadad, a.k.a. Abu Ousayd, a central figure in the Salafi and jihadi community in Australia and among English-speaking jihadis on social media, posted a brief video on his Telegram channel, in which he stated that "our aim" is for Islam to dominate all ways of life, institutions, and societies. To achieve this, he called for "establishing a khilafah [Caliphate] based upon the foundations laid down by the Prophet Muhammad."
The short video, which included English subtitles, depicted a hand raising the Quran at what appears to be a mosque congregation, with Abu Ousayd saying: "We call to the deen [religion] of Allah Subhanahu Wa Ta'ala [Almighty Allah], and we wish for it to dominate." He added: "And it will dominate all other ways of life, even if the disbelievers they hate it, [and] even if the mushrikeen [polytheists] detest it."
Abu Ousayd continued: "Allah Subhanahu Wa Ta'ala will establish this deen [religion] on this earth when Allah Subhanahu Wa Ta'ala chooses. But it's up to us to want to be part of this establishment, to work for this establishment, to work for the deen of Allah Subhanahu Wa Ta'ala, to work for this aim."
He then added: "We aim to establish Allah's religion in its entirety in every soul and upon every inch of this earth. In every home, institution, and society. To achieve this, we must first succeed in bringing people to the worship of their Lord. And two, establishing a khilafah [Caliphate] based upon the foundations laid down by the Prophet Muhammad."

According to a biography posted on his website, Abu Ousayd is "a strong voice for many voiceless Muslim Prisoners in Australia and a pioneer in activism against injustice."
