"America is strengthened by the countless contributions of our Muslim citizens, and we value our ties with Muslim nations throughout the world," he said in a statement marking Eid al-Fitr.
The US president marked the celebration without noting that Iraq had suffered through its bloodiest Ramazan since the March 2003 US-led invasion to topple Saddam Hussein.
"For people of all faiths, Eid al-Fitr is an opportunity to reflect on the values we share and the friendships that bind all who trace their faith back to God's call to Abraham," said Bush.
"(First Lady) Laura (Bush) and I send our best wishes for a joyous Eid and for health, happiness, and prosperity in the year ahead," he said.
