The law of Adam prescribed the worship of Allah, prayers, fasting, abstinence from wine and pork; and the opinion that wine was first made in Jamshid’s time is not deserving of any credit. His book [i.e. Adam’s] contained forty pages; some say twenty-one. It treated on the secrets of natural philosophy, the knowledge of useful and noxious things, medicine, the way of subjecting Jinns and devils, geometry, arithmetic, and other sciences.
