AAOIFI Standard 21 · Re-screened daily · Cross-checked across independent sources
Know the moment a holding stops passing our Sharia screen.
A company's compliance result can change — it takes on debt, or an acquisition adds non-compliant revenue. HalalStock watches every holding you own, re-screens it daily against AAOIFI Standard 21, and alerts you the moment one stops meeting the criteria. Check any stock free to start.

Compliance isn't permanent.
A halal stock today can fail next quarter — debt creeps over the line, an acquisition adds non-compliant revenue, interest income climbs. A one-time check goes stale. So we re-screen every holding you own or watch every day, and tell you the moment its status changes.
Daily re-screening
Every stock you own or follow is screened again each day against the latest financials — never a one-time snapshot.
Status-change alerts
The instant a holding crosses from compliant to non-compliant (or back), we email you — with the exact ratio that moved.
Early-warning watch
When a passing ratio drifts close to its limit, we flag it as at-risk — so a flip never catches you by surprise. Every number is checked and dated.
Cross-checked. Never guessed.
Every figure behind a result is cross-checked across independent sources — SEC EDGAR, Yahoo and Finnhub — and screened against AAOIFI Standard 21. At least two sources must agree, or the figure is flagged unverified and we say we can't confirm. A result you can actually trust.
Three independent sources
SEC EDGAR filings, Yahoo and Finnhub — each figure must agree across them before we treat it as fact.
Unverified is flagged
Under two sources? The figure is marked unverified and the verdict says it can't confirm — rather than passing a guess off as a fact.
Show your work
Every verdict comes with the ratios, the thresholds, the sources used and the reasons — so you can see exactly why, not just the answer.
How it works
The recognized AAOIFI Standard 21 methodology — two stages, fully transparent.
Stage 1 — Business check
Excludes non-permissible activities. Knows Islamic banks & takaful are compliant.
Stage 2 — Financial ratios
Debt < 30%, cash + interest securities < 30%, impure income < 5%.
When data is missing or in a different currency, we say we can't confirm rather than guess — see the trust section above.
