Although Sultan wanted to be a writer, and would have preferred to study Arabic literature, she studied at the medical faculty at the University of Aleppo due to pressure from her family. She says that she was shocked into secularism by the 1979 atrocities committed by Islamic extremists of the Muslim Brotherhood against innocent Syrians. She states that while she was a medical student, she witnessed the machine-gun assassination of her professor, Yusef al Yusef, an ophthalmologist from the university who was renowned outside Syria. "They shot hundreds of bullets into him, shouting, 'Allahu Akbar!' " she said. "At that point, I lost my trust in their god and began to question all our teachings. It was the turning point of my life, and it has led me to this present point. I had to leave. I had to look for another god." She worked for four years as a psychiatrist in a hospital.
