Plain-English Summary
Compliant under AAOIFI, DJIM, S&P (debt/MC 15.2%, under their 30–33% caps), but fails FTSE, MSCI on debt/assets 43.3% > FTSE 33%, MSCI 33%.
Why Screeners May Disagree on MRK
AAOIFI's two recognized ratio bases disagree for MRK: the market-capitalization reading (per Shari'ah Standard 21 §3/4) is compliant, while the total-assets reading (used by FTSE/MSCI-style screeners) is non-compliant (debt/assets 43.3% > 30%). Apps using different bases will legitimately differ on this stock.

Purification
Purification rate: 0.53% of income
The purification rate estimates the share of the company's income attributable to impure sources (primarily interest). Scholars recommend donating that share of any dividends or gains to charity. Use the terminal's purification calculator for exact amounts on your holding.

A stock that has screened comfortably for eight straight quarters is a different story from one that crossed a threshold last quarter — trajectory shows which one this is.
