[1] The construction of the Assalam Mosque was largely funded by wealthy Qatari Bader Abdullah Al-Darwish, the chairman of Darwish Holding, who donated €4.4 million to complete the building.

Bader Abdullah Al-Darwish is also a member of the Board and the Executive Committee of Qatar National Bank.

[citation needed] A 1905 law in France enforcing the separation of church and state has led to funding issues for the construction of places of worship in France, leading wealthy donors, such as the Qataris, to step in and finance this construction.

[3] Prior to the construction of Assalam mosque, a small church was given to the UOIF for the purpose of Muslim worship.

The building features soft natural light to create a tranquil space for worshipers.
