"After the Farhud, life changed drastically for the city's Jews. Up to that point Haddad had had many Muslim friends.
"Suddenly I changed my attitude. I didn't feel any more Iraqi. I felt I'm a Jew and I vowed that I wanted to kill an Arab," he says.
One day, swimming in the River Tigris, he encountered a drowning man, and instinctively helped him to the shore.
"When I came home I was shook up. Not because I saved the guy but because I didn't follow my vow to kill an Arab. And when I went to see the rabbi, he said, 'You can't make a vow to kill. You can only make a vow to help.'
"That's what stimulated me to go into medicine, actually. I knew that I want to save lives, not to kill people."
