Is it permissible to bury a Muslim in a non-Muslim cemetery if no Muslim graveyard is available?

Yes, when genuinely necessary — the strongly preferred and default practice is burial in a dedicated Muslim graveyard, but if no Muslim cemetery is realistically accessible, scholars generally permit burying a Muslim in a general or non-Muslim cemetery, provided the grave itself is set apart from non-Muslim graves as much as practically possible and the burial otherwise follows correct Islamic procedure (facing the Qibla, etc.). This situation is common for Muslim minority communities in many countries and is treated as a matter of necessity (darurah), not a compromise of core belief.

Where any choice exists, families should still prioritize a Muslim burial ground or a distinctly Muslim section within a shared cemetery, since scholars note this matters for reasons including the du'a and treatment traditionally extended between Muslim graves. But the underlying principle — that a proper, dignified Islamic burial should not be delayed or denied over the type of cemetery when no real alternative exists — is well established across fatwa bodies.
