DETROIT — No. Contrary to Donald Trump’s claim, Muslims on Jersey City did not celebrate the 9/11 terrorist attack. But this year, a major Muslim holiday coincides with the 15th anniversary of the tragic incident.

If you see your Muslim friends and neighbors celebrating and exchanging joyous greetings next Monday, know that it has nothing to do with 9/11.  

Eid al-Adha, one of the most sacred occasions on the Muslim calendar, celebrates the yearly Hajj pilgrimage to Mecca. This year, it will likely fall on Monday, Sept. 12.

Islamic holidays are observed on the Muslim lunar calendar; their dates on the Gregorian calendar vary annually.

David Gelios, FBI special agent in charge of the Detroit division, urged citizens to remain vigilant and report any suspicious or concerning activities during the coinciding occasions.

“With these two events being in such close proximity to each other on the calendar, it has been suggested individuals may misinterpret celebratory activities associated with the celebration of Eid al-Adha as a celebration of 9/11,” he said in an email to the AANews publisher. “As such, some could use this as an opportunity to cause disruption in our community.  Currently, our office does not have any credible threat information regarding the remembrance of 9/11 or the celebration of Eid al-Adha.”

Gelios encouraged calling the local police department or the Detroit FBI to alert the authorities to anything out of the ordinary.

The number to the local FBI office is 313-965-2323.
