Diamondback Energy is an independent oil and gas producer in the Permian Basin (Texas), among the largest there after merging with Endeavor. Its money comes from oil and gas sales.
What was checked

Figures from the company's filings (2026-06-30), USD. Market cap is a 36-month average (the S&P Shariah index approach), so a one-day price move does not flip the verdict. Today's market cap: $57.06B.
For information (AAOIFI 3/1 note): cash + receivables are 3.4% of total assets (2026-06-30). AAOIFI recommends tangible assets of at least one third — this figure does not affect the verdict, and other major screeners do not apply it either.
