HALAL — SCREEN DOES NOT PASSstock

Is MLI Halal?

Copper, brass, aluminum and climate-products manufacturing — generally permissible activity, but the current liquidity and receivables screens fail.

A licensed historical market-cap series is not stored; the total-assets liquidity and receivables screens already fail.

Business-activity disclosure

Mueller manufactures copper, brass, aluminum, plastic, piping and climate/HVAC components. The core manufacturing activity is generally permissible, while downstream end-use allocation remains qualitative.

Limitation: The filing does not provide a universal prohibited-revenue numerator across product and customer categories.

Purification

The filing discloses $11.870 million of interest income, but no scholar-specific purification instruction or universal prohibited-revenue numerator is provided.

Inputs, assumptions and primary sources
  • Amounts are USD millions from Mueller Industries' March 28, 2026 Form 10-Q.
  • Mueller reports no debt; the $22.824 million total combines current and noncurrent operating lease liabilities for a conservative debt perimeter.
  • Cash is $1,382.345 million and short-term investments are $20.696 million.
  • Receivables are $670.511 million, quarterly revenue is $1,193.005 million and disclosed interest income is $11.870 million, approximately 0.99% of revenue.
  • Copper, brass, aluminum, plastic, piping and climate products are generally permissible, but no universal prohibited-revenue numerator is asserted.

This is a reproducible financial screen, not a fatwa. A failed total-assets screen can coexist with a pass under a market-cap methodology. ZakatInvest keeps the qualitative assessment separate so numerical thresholds do not erase material context.
