Imam's knowledge of his death and its problem about its incompatibility with infallibility

The discussion, Imam's knowledge of his death, is one of the issues of the Imam's realm of knowledge. This issue can be investigated in both rational and transmissive ways. It comes from the general and specific narrations about the scope of the Imam's knowledge that the Imams of the Prophet (pbuh) were aware of their time and how they were died. This raises the question why they did not protect their lives which is rationally and legally obligatory. Is this not incompatible with the infallibility of the Imam? The present article examines this issue and, after quoting narrations related to the Imam's knowledge of the time of his death, presents the answers which Shiite scholars have provided, some of which have been quoted in some traditions.
