The 64-year-old Muslim doctor from Lothian, Maryland, along with a few volunteers, spends Friday mornings providing flu shots, measuring blood pressure and offering other health treatments at a Guatemalan consulate in Silver Spring, Maryland.

Here, patients file in, one after another, for the Pakistan native’s treatments.

Spread by word-of-mouth, the clinic sees patients from across Maryland and nearby states.

Salvadoran Alfredo Moran, a resident of Manassas, Virginia, drove an hour and a half to the free clinic on a recent Friday. The 80-year-old car washer was suffering from a fever and high blood pressure.

Moran, a U.S. citizen, told the University of Maryland’s Capital News Service through a translator that he has a primary care physician and is insured by Medicare, but rising prices and limited coverage deter him. Meelu provided him with medication for his fever, a prescription to get his blood pressure under control and told him to return in two weeks.

Luis Morales is a 47-year-old Glen Burnie, Maryland, resident, originally from Guatemala. He said the free clinic is very helpful. Morales is not a United States citizen and is uninsured, thus finding health care poses an issue.

“I didn’t want to miss the opportunity,” Morales said about the clinic through a translator. After a friend informed him about the clinic, Morales decided to make the 50-minute drive to inquire about his regular headaches. Meelu diagnosed the root cause to be high blood pressure and sent him home with medication to treat it.

Meelu said he hopes his service sheds a positive light on Islam, especially in recent times of terror.

“I really feel ashamed when I see the stories on the TV of what ISIS is doing,” Meelu said. “These people are really giving a bad name to Islam. That is not our teaching. That is not our goal. I hope what we do assures people.”

And, Meelu said, the rhetoric of President-elect Donald Trump on Muslim immigrants is worrisome to the Ahmadiyya community.
