Which of the prophets are still alive?
Concise answer
Dear User,
Allamah Tabatabai (RA) interpreting the verse 65 of Surah al-Kahf (Then they found one from among Our servants whom We had granted mercy from Us and whom We had taught knowledge from Ourselves[1]) appertained to Prophet Moses (AS) and Prophet Khidr (AS) quotes narrations from a number of Sunni and Shia sources about some prophets being alive.
Among the narrations he has quoted is a tradition from Jalaluddin in his Al-Durr al-Manthur which is narrated from Shahin from Khasif that says:
«أربعة من الأنبیاء أحیاء اثنان فی السماء: عیسى و إدریس، و اثنان فی الأرض الخضر و إلیاس- فأما الخضر فإنه فی البحر و أما صاحبه فإنه فی البر»[2]
Four of the prophets are alive two of whom are in the heavens: Jesus and Edris, and two of them are in the land: Khidr and Elias, Ilyas (Elias). As for Khidr, he is in the sea but his companion is in the land."[3]
It should be noted that this narration is also available in Shia sources but it has been narrated from Sunni sources.[4]
