The mosque cost 7.5 million to build, the mosque's cornerstone was laid on Saddam Hussein's 61st birthday on 28 April 1998. It was formally completed on 28 April 2001 in time for the ten-year anniversary of the Gulf War. The association became a
de facto al-Qaeda ally; its leader
Harith Suleiman al-Dhari, who operated out of the mosque, is said to have played a key role in mobilizing insurgents during the
2004 fighting in Fallujah, west of Baghdad. In 2004, the mosque saw a gathering of around 200,000 Muslims, both Sunni and Shi'a Muslims, to denounce the US-led occupation and pledge solidarity with the people of
Fallujah as well as the uprising led by the Shi'a cleric,
Muqtada al-Sadr. Dr. Harith al-Dhari, the preacher of the Mosque at the time, gave a speech denouncing the US-led occupation and
democracy. Reportedly, al-Dhari was seen crying due to what was happening at Fallujah at that time. After the gathering was over, a boycott of
American and
British goods was called into action. In 2007, the association was expelled by the
Sunni Endowment, a quasi-governmental agency responsible for Sunni mosques in Iraq, which took control of Umm al-Qura. On 28 April 2023, a fire broke out inside the mosque after the burning of three caravans surrounded by weed and plants. The fire department fought the fire. == Architecture ==
