Le Juste Milieu (from Arabic: الوسط, al-waṣaṭ, "the middle") is the name of an Islamic association and the first Islamic center in Luxembourg. The center's construction was largely funded by Qatar Charity, an organization that has extensively been accused of funding terrorist and extremist activities. Qatar Charity and Le Juste Milieu worked together to found the Islamic center. It was opened in May 2015 by Qatar Charity's chairman, Sheikh Hamad bin Nasser bin Jassim Al Thani.
The overall cost of the project was around 2.2 million euros of which Qatar Charity paid about 75 percent. Le Juste Milieu previously rented the property and had wanted to purchase it due to frequent changes in ownership. Qatar Charity initially began funding the project by selling shares to collect the sufficient funds to cover its construction. They turned to Qatar Charity for help purchasing the property.
