If it has completed its allotted cycles of transmigration [tanasukh], it is transferred into the crop of a bird of its kind, being punished until the Day of Disclosure. If some cycles of transmigration remain for it, it is returned into structures [hayakil] until it fulfills its obligation and remains according to its merit."

"As for the believer, when their soul leaves the body, it is dipped in a spring called the Spring of Life, and it tastes every pleasure it experienced in the worldly abode throughout all its shirts [qumus]. Then it is deposited in the crop of a bird of its kind, grazing on the finest food and neighboring everything beautiful and the Master Messenger (PBUH) said: "If the world were flowing blood, the believer's sustenance from it would be lawful [halal]." And Allah knows best.

"Because it is the soul that intends, so there is a killer and a killed."

Thawa [to stay/dwell] means to die; thus the soul of the associate remains. For when a believer is killed by a sword or otherwise, they are transferred to a state more honorable than they were in. And when a disbeliever dies, they are transferred to what is lower than they were in, as it was narrated:

"When the soul of the Opponent [Mukhalif] leaves, it is dipped in Sijjin and tastes every bitter punishment it had previously undergone and what it shall receive in the future; it forgets the human pleasures it once had.
