Who is the longest-lived human being? Is it Al-Khidr, or Elias, or Noah, or someone else?

The oldest living human has not been specified, but Noah, peace be upon him, was among the longest-lived of mankind, as he remained among his people for a thousand years, save fifty, before the flood, and lived for a period after it. Narrations have differed regarding his total age. Scholars have also differed concerning the lives of Al-Khidr and Elijah, while texts have indicated the lives of Jesus and the Dajjal (Antichrist), making them among the longest-lived people. It is advised to focus on what benefits one in religion and worldly life instead of determining the oldest living human.
