One cold winter night, Syrian Ibrahim Othman went out to pray and came home cradling a baby girl, abandoned at the doorstep of the village mosque just hours after she was born. "I took her home and told my wife, 'I brought you a gift'," said the 59-year-old resident of Hazano, in rebel-held northwest Syria. He named the baby Hibatullah, meaning "gift of God", and decided to raise her as one of the family.
