When I do a search for this online, due to The Scarab God's copy ability, I was unable to find the answer I was looking for.
My opponent has The Scarab God on the battlefield.
I cast Clone - choosing to have it enter as a copy of The Scarab God.
My opponent kills my copied The Scarab God. Scarab God's final ability sets up a delayed trigger (I presume) to return it from your graveyard to your hand at the next end step.
However, my Scarab God is now a Clone in my graveyard. Does this mean the delayed trigger does nothing at end step or do I get my Clone back to my hand from graveyard?
When Clone-turned-The-Scarab-God dies (assuming that permanent isn't a token), you still return the card it became in the graveyard to its owner's hand at the beginning of the next end step, no matter what card it is (C.R. 603.6c, 700.4; the words "it" and "its" on The Scarab God's last ability refer to that card regardless of its nature [C.R. 400.7h, 400.2]).
EDIT (Nov. 21): Note also that that Clone-turned-The-Scarab-God's last ability looks at the state of the game just before that permanent dies (C.R. 603.10a, 603.10), which is why that ability triggers at all.
EDIT (Feb. 18, 2020): Add rule citations. Minor edit.
