This passage discusses some preliminary points about Islamic economics: 1. Islamic economics is based on the belief that God has provided divine guidance covering many aspects of life, not just worship. This guidance balances allowing human intellect with establishing eternal principles. 2. Human reason has limits and can be confused by desires, leading to errors. Past theories seen as irrational today were once considered rational. 3. Islam leaves a wide scope for human judgment but subjects activities to principles with eternal application that cannot be violated for expediency. The goal is to avoid extremes and have a balanced approach to governing life.
