الْإِفْنَاءُ تَفْرِيقُ الْأَجْزَاءِ لِلْأَجْسَامِ، وَالْإِعَادَةُ جَمْعُهَا
Annihilation is understood as the dispersal of bodily components, and restoration as their reunion.
On this account, the organism's worldly structure ceases, but the constituents on which bodily identity depends need not be reduced to sheer nonexistence. Divine power reunites them into a body.
The account is supported by reference to the gathering of the birds' parts in Abraham's story and other texts. Its decisive distinction is between dispersion and absolute nonexistence: the former does not necessarily entail the latter.
