Praise be to Allah, and may peace and blessings be upon the Messenger of Allah. To proceed:
This report was narrated from Al-Hasan Al-Basri, may Allah have mercy on him, with the wording: “Indeed, Jesus did not die, and he will return to you before the Day of Judgment.” Al-Tabari and Ibn Abi Hatim narrated it as a report attributed directly to the Prophet ﷺ.
However, its chain of transmission is very weak, and this hadith cannot be used as evidence, due to several defects:
Abu Ja‘far Al-Razi was considered weak by a number of leading hadith scholars. They described his narrations as prone to error and objectionable, so reports in which he is the sole narrator cannot be relied upon.
‘Abdullah ibn Abi Ja‘far was criticized by scholars. Ibn Hibban stated that his narration should be considered only when it is supported by reports other than his narration from his father.
Al-Rabi‘ ibn Anas: Scholars have pointed out that his narration from Abu Ja‘far Al-Razi contains considerable inconsistency.
The narration is mursal: Al-Hasan Al-Basri did not meet the Prophet ﷺ. Therefore, his narration from him is considered mursal, and the mursal narrations of Al-Hasan are regarded among the weakest types of mursal reports by a number of hadith scholars.
Accordingly, this hadith is not established as being authentically narrated from the Prophet ﷺ through this chain, although the descent of Jesus, peace be upon him, at the end of time is established through other authentic hadiths.
And Allah تعالى knows best.
