Apart from Prophet Isa (Alaihis-salat-wassalam), is there any other living soul that is alive until end of time?

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

There is no person alive till the end of this life except Jesus (Essa) . However the people of the knowledge have different opinions regarding Khidar and Prophet Ilyas (peace be upon both of them). The most correct opinion is that Khidar and Prophet Ilyas (peace be upon both of them) are not alive but they died. Imam Ibn Katheer said "that the Ahadith that prove that Khidar and Prophet  Ilyas are alive, and that they meet every Ramadan in Bait Al-Muqaddas and perform Hajj.", etc. are all incorrect.

Allah knows best.
