A few weeks ago, I found myself sitting in the home of Imam Salahuddin Barakat in the Swedish city of Malmö. I’ve just met him for the first time; but his other guest, Rabbi Moshe David HaCohen, is a regular here. As the imam serves Arabic coffee and kosher cinnamon buns, I adjust my camera and the rabbi, with a notable air of familiarity, makes himself at home on the couch.
