Saudi authorities have arrested a man who claimed to have traveled to the Muslim holy city of Mecca to perform an Umrah pilgrimage on behalf of the late Queen Elizabeth II.

The man, a Yemeni national, posted a video clip of himself at the Grand Mosque in Mecca, Islam’s holiest site where non-Muslims are banned, on social media on Monday.

In the clip, he held up a banner that read, “Umrah for the soul of Queen Elizabeth II. We ask God to accept her in heaven and among the righteous.”

The footage was shared widely on Saudi social media, with Twitter users calling for the man’s arrest.

Saudi Arabia bans pilgrims to Mecca from carrying banners or chanting slogans.

And while it is acceptable to perform umrah on behalf of deceased Muslims, the same is not true for non-Muslims like the Queen, who was supreme governor of the Church of England, the mother church of the Anglican world communion.

Grand Mosque security forces “arrested a resident of Yemeni nationality who appeared in a video clip holding a banner at the Grand Mosque, violating the regulations and instructions for the Umrah,” state media said in a statement late Monday.

“He was arrested, legal action was taken against him and he was referred to the public prosecutor’s office.”

State television broadcast segments about the incident that included the controversial video clip, but with a blurred banner.

Umrah is a pilgrimage that can be undertaken at any time, unlike Hajj, which takes place once a year and usually attracts millions of people from all over the world.

The Queen died on Thursday and her funeral is scheduled for September 19.
