Is MLM Halal?
Aggregates and construction-materials producer — a permissible building-materials business.
What You Should Know
Martin Marietta Materials, Inc. supplies crushed stone, sand, gravel, cement, and other construction aggregates used in roads, infrastructure, and buildings. Producing and selling construction materials is a clearly permissible activity with no haram revenue line. Martin Marietta carries debt from acquisitions and quarry investments, so its total-debt-to-market-cap ratio is the primary screening item and should be confirmed against the 33% threshold; it has generally screened within range. Interest income on cash is incidental and should be checked against the 5% threshold and purified.
⚠️ Concerns
- •Carries acquisition-related debt — confirm total debt / market cap stays under the 33% threshold against the latest filings
- •Incidental interest income on cash should be checked against the 5% threshold and the corresponding portion of returns purified
- •Cyclical with construction and infrastructure spending — re-screen the ratios periodically
