All that is on earth is to perish.
Everyone on earth perishes.
All that live on it will perish
Which then of the bounties of your Lord will you deny
Each/every who (is) on it (is) vanishing/being destroyed
Whatever which exists on earth will eventually perish…
For everything on the earth is extinction
All that is on earth will pass away
Whoever is on the earth will perish
All that is on it (- the earth) is subject to decay and doomed to pass away
Whatsoever is on it (the earth) will perish
