Is SLB (SLB N.V.) Halal or Haram?

Based on our AAOIFI-standard shariah screening, SLB is Halal and considered permissible for Muslim investors. It passed all 4 of 4 compliance screens including business activity review, debt-to-market-cap ratio (14.78% vs ≤33% threshold), interest income ratio (0.61% vs ≤5% threshold), and cash & securities ratio (5.06% vs ≤33% threshold).

SLB N.V., formerly known as Schlumberger, is a global leader in providing technology and services to the energy sector. The company operates across four main divisions—Digital & Integration, Reservoir Performance, Well Construction, and Production Systems—offering everything from hydrocarbon production optimization to carbon management and subsurface geology evaluation. For Muslim investors, SLB represents a solid shariah-compliant opportunity in the energy sector. The stock successfully passes all four AAOIFI screening criteria, meaning its core business activities and financial structures align with Islamic finance principles and it is considered Halal for investment. From a financial perspective, SLB demonstrates strong compliance metrics that halal investors look for. The company operates with a very manageable debt-to-market cap ratio of 14.8% and carries minimal interest-bearing cash reserves, with interest income making up just 0.61% of total revenue. While the core business of oil and gas technology is universally accepted as halal, investors should continue to monitor SLB's debt levels during inevitable energy market fluctuations. As the company expands into new energy transitions and carbon management, ensuring these new ventures remain free of impermissible financial structuring will be key to its ongoing compliance. SLB N.V. operates in the Energy sector under the Oil & Gas Equipment & Services industry and is headquartered in Houston, TX, US. The company is led by CEO Olivier Le Peuch and employs approximately 110,000 people.

SLB was screened using AAOIFI-based shariah compliance criteria. Four tests are applied: (1) Business Activity — the company's core business must not derive primary income from haram (prohibited) activities such as alcohol, gambling, tobacco, or interest-based finance. (2) Debt-to-Market-Cap — total debt must not exceed 33% of market capitalization. (3) Interest Income — interest income must not exceed 5% of total revenue. (4) Cash & Securities — cash and interest-bearing securities must not exceed 33% of market cap. SLB passed 4 of these 4 screens.

Although SLB passes all shariah screens, it does earn $217.0M in interest income (0.61% of revenue). Many scholars recommend purifying this portion by donating the equivalent percentage of any dividends received to charity. For example, if you receive $100 in dividends, you would donate approximately $0.61 to purify the income.

SLB was last screened on 2026-04-29. Shariah compliance status can change as companies report new financial data, acquire new businesses, or shift revenue streams. We recommend checking back periodically for the most up-to-date screening results.
