Ivanka Trump’s celebratory message for Muslims recognizing the Islamic holiday of Eid al-Adha today backfired when social media users reminded her that her father has barred people from Muslim-majority countries from traveling to the United States.

“Eid Mubarak to Muslims all around the world celebrating Eid al-Adha,” she tweeted on Sunday. “Wishing you health, happiness and joy!”

The phrase “Eid Mubarak” means “blessed feast” and is a common greeting among Muslims on what is known as the Festival of the Sacrifice. It is the second of Islam’s two major holidays, and honors the test of faith endured by the Prophet Ibrahim.
