On Sunday, President Obama and First Lady Michelle released a statement thanking Muslim Americans for their many “achievements and contributions… to building the very fabric of our nation and strengthening the core of our democracy.”

The comments were made to mark the celebration of Eid-al-Fitr, a time of spiritual renewal for Muslims which comes at the end of the month-long fast of Ramadan. The Obamas said in their statement that Eid “celebrates the common values that unite us in our humanity” and “welcomed their commitment to giving back to their communities.” The International Business Times reports that during Eid, Muslims join in Islamic prayer, while saying “Allahu Akbar,” or “God is Great,” and feasting.

The statement further reads that the administration “wishes Muslims in the United States and around the world a blessed and joyous celebration.” The letter ended with salutation of “Eid Mubarak,” which roughly means “blessed celebration.”
