Rule 603.6e
Official source text from the 15 February 2021 Rules release
Some Auras have triggered abilities that trigger on the enchanted permanent leaving the battlefield. These triggered abilities can find the new object that permanent card became in the zone it moved to; they can also find the new object the Aura card became in its owner’s graveyard after state-based actions have been checked. See rule 400.7.
