Wearing a headscarf gave her an immediate feeling of respect, as well as a sense of privacy and distance from strangers who felt compelled to stroke her lovely long locks.
Since then, Ul-Hasan has worn a hijab every time she has gone out in public — whether to run an errand, pick up a child at school, attend services at the mosque or participate in interfaith gatherings.
For her, the scarf was a point of pride and an act of faith. But given the horrific murders in San Bernardino, Calif., and Paris — and the anti-Islamic backlash in some quarters — she is considering removing it.
"I feel so lost, troubled for Muslims and for everyone," Ul-Hasan wrote Monday on her Facebook page. "Am I to live in fear [or] do I remove my headscarf so I don't have to stick up for my faith continually? Should I remove my identifiers and blend in?"
It is not a hypothetical question for the longtime advocate of interfaith relations.
As a Muslim woman, Ul-Hasan feels somewhat hopeless about convincing outsiders that mass murderers "do not represent the several million Muslims who live in the United States."
She serves on Cottonwood Heights' Board of Adjustment, Utah's Civil and Compassionate Communities committee, the Salt Lake Interfaith Roundtable, and other diversity and school councils.
Through all of her activism, she writes in an email, Ul-Hasan wants to persuade Utahns "not to be afraid of us Muslims. ... What else can I do except deny these [terrorists] as members of my faith or any faith because we all know there is no God or Allah that condones these horrible acts."
Imam Muhammed Mehtar of Khadeeja Islamic Center in West Valley City shares that view.
"Islam does not favor such violence. Islam condemns all acts of terror. Killing people is just wrong," Mehtar writes in a news release. "As an imam, I find these actions reprehensible and unacceptable."
He hopes Muslim communities around the nation "will not be implicated for this barbaric act committed by these people."
The imam offers condolences to the people of San Bernardino, but also to those in Colorado Springs who were affected by the recent mass shooting at a Planned Parenthood clinic.
"Our heart goes out to each man, woman and child who lost a loved one. People must realize, as they study the Christian faith, that Christianity does not preach violence," Mehtar writes. "We hope that Christians are not being similarly stigmatized due to the actions of one individual."
President Barack Obama has echoed Mehtar's concerns about blaming all Muslims.
