SIF demonstrates non-compliance with Shariah standards primarily due to a critically high debt ratio of 88.21%, far exceeding all financial thresholds, despite compliant liquidity and income ratios. The company's involvement in defense-related activities through aerospace forging contributes additional compliance concerns, potentially requiring purification or avoidance. No inclusion in major Shariah indices reinforces the non-compliant status. Investors should monitor debt reduction efforts and consult scholars on defense sector permissibility. Overall, the stock is not recommended for Shariah-compliant portfolios without significant restructuring.
