Examining the most Important Proofs of Cancellation of Reincarnation (Avicenna's and Mulla Sadra's Proofs) and the Necessity of Using the Concept of Time in Sadr al-Motaalehin's Proof

Islamic thinkers including philosophers and theologians, have presented various proofs to reject the belief in reincarnation which some of them have been challenged by other thinkers. Among them, two proofs have special importance and status, one attributed to Sheikh Al-Raees Ibn Sina and the other to Mulla Sadra. İn this paper after criticizing and investigating the above two proofs and stating their problems, it is atempted to present new version of Sadr al-Motaalehin proof which is based on time concept. Considering that the concept of time is common between philosphy and science, another aspect of Sadr al-Motaalehin's proof is paid attention to and its validity is examined from this point of view. Also, this descriptive and analytical article shows that Sadr al-Motaalehin's proof which is rooted in the substance theory, is the most convincing proof in reject the reincarnation. It should be noted that this goal can be achieved by using the concept of time in this proof and presenting an interpretation based on the concept of time.
