"I was so upset when Al Qaeda forced the Shia out of here," he says between drags off a water pipe, "we liked them, they were our neighbors."
At nearly 80 years old, Ahmed Hassan al Taha, the Imam of Abu Hanifa Mosque, a prominent Adhamiya landmark, says he can still remember the days when talking about sect in Iraq was taboo.
"It used to be a matter of shame for someone to identify as Sunni or Shia or Kurd," he explained from behind a desk piled high with books. "We used to live in a peaceful way, in a modern way, like the countries outside of Iraq."
He admits that now there are what he describes as isolated incidents of Shia militias abusing their power, but he called the talk of increased sectarian tensions and reports of Sunnis fleeing in large numbers "just propaganda."
"We have a very good relationships as people. Just across the bridge," he said, referring to the predominantly Shia neighborhood of Kadhimiya on the other side of the Tigris River, "you can find the same faces, the same mercy. We are all people of mercy."
But tolerance like this is by no means shared by all in Iraq these days. For many residents, escalating violence that's hitting closer and closer to home is bringing ugly prejudices bubbling to the surface.
"These people, they are not like us," whispers a Sunni woman who asked to be called Um Mariam, indicating a Shia man just across the room.
After one of her neighbors was killed in his own home, she said she decided it was time flee. But because flights out of Baghdad are booked solid for weeks, she's come to the Iraqi Airways office run by the Shia-controlled Transportation Ministry to try to call in a favor.
"Just look at the shape of his face, it's not like us, even the way they eat, just with their hands."
She says most of her family has already fled Baghdad and as soon as she can get a ticket she'll do the same.
"Our future," she says, referring to Baghdad's Sunnis, "it’s finished."
