What HMS can tell you
Is In-N-Out HMS certified?
No. HMS does not certify In-N-Out, and HMS has not inspected the slaughterhouses, processors or distributors that stand behind the meat served at In-N-Out. HMS cannot confirm that it is Zabiha Halal.
The standard HMS applies
We certify only what we check. For meat that means a permissible animal, slaughtered by hand Zabiha while it is alive, with Bismillah pronounced for each animal, and an unbroken chain of approved suppliers afterwards. Word of mouth, a review or a delivery listing cannot establish it, as what HMS certified really means and why machine slaughter is not Zabiha set out.
Certification is issued per location and can be limited to particular products, so any certified In-N-Out location would be shown in the HMS certified directory.
Asking questions is not rude, and staff are used to them. Ask who certifies the meat and which supplier is used, then confirm the answer independently, because a sincere answer at the counter is still not the same thing as verification.
Our advice: avoid it and eat HMS Certified only
Do not gamble with your deen. If it is not verified, leave it. That is the Prophetic guidance:
“Leave that which causes you doubt for that which does not cause you doubt.”
Until HMS can confirm In-N-Out, the safe path for a Muslim is to avoid it and eat only from HMS Certified kitchens, where the supply is monitored from the slaughterhouse to your plate. Find an HMS Certified place near you.
