In the last few decades, a lot of interest has been generated in the study of economic thought in Islam. In spite of several works published on the subject, not much has been written on economic ideas of Ali, who was one of the most prominent caliphs (deputies) of the Prophet of Islam. Not much is known on the economic, political and administrative policies Ali pursed and moral values he upheld even in the most trying circumstances. The present work attempts to fill this vacuum. A dispassionate study of the economic ideas of Ali makes it clear that he was a distinct precursor to several economic values, which continue to dominate even today, the mainstream economic thinking world-wide. He excelled, in both letter and spirit, to solve whenever a new economic problem confronted him. The justification, which Ali provided, was amazingly incredible and never heard before. His ideas may be rightly termed as Alinomics.
