Are there any basic, clear courses, books, or educational materials that thoroughly explain the rules for auditing companies according to AAOIFI standards? I am most concerned about the complexity of financial analysis, specifically how to interpret financial statements, correctly calculate an acceptable debt level, and ensure that dividends are free from usury (riba). I’d like to find a practical resource with real-world examples, not just dry theory, so I can quickly learn the basics and avoid making mistakes that are haram right at the start of my journey.
