Reincarnation is one of these matters, such that the naming itself has several synonyms, which are transmigration (Al-Tanasukh) and its four types:

Naskh: which is the transition of the soul into a human body.

Maskh: the transition of the soul into an animal.

Raskh: the transition of the soul into an inanimate object.

Faskh: the transition of the soul into a plant.

Reincarnation is also called "the return to embodiment," and it is called "re-embodiment." Some Theosophical researchers prefer the expression "re-embodiment" instead of reincarnation due to the erroneous concepts that have attached to the latter. However, the common and currently most circulated Arabic word is Al-Taqammus (Reincarnation), and it means the soul wearing a new bodily shirt (Qamis), pursuant to the law of Karma—and it means the Merciful, the Just, the Law of Requital.
