Proof of the existence of the Imam of the Time (AS) in the light of the traditions of "Knowledge of the previous Imam to the next Imam"

In the authentic Shia hadith sources, about forty narrations indicate that every imam knows the imam after him, and entrusts the responsibility and trust of the imam to him. These narrations - which are divided into different categories according to their meanings - indicate the existence of Imam Asr (AS) during the lifetime of Imam Hasan Askari (AS) and the present and future times. In this research, using the narrative and analytical method, the validity of the document of the traditions and how they indicate the existence of the Imams of the time (AS) from the time of the martyrdom of their honorable father to the present time have been investigated.
