Will the companions of Prophet Jesus (peace be upon him), upon his return, be able to reach the level of the Companions [of Prophet Muhammad], and how long will he remain on Earth?

The companions of Prophet Jesus, upon his return, cannot reach the level of the companions of Prophet Muhammad, peace and blessings be upon him, for scholars have agreed that the Companions are superior to all others. The Companions are better than the disciples of Jesus and the followers of other prophets, as affirmed by Quranic texts and prophetic traditions.

Jesus, peace be upon him, will remain on Earth for forty years after his descent, then he will pass away, and the Muslims will pray over him. As for the seven years mentioned in another hadith, that refers to the duration people will remain alive after his death.
