Silsilah as-Sahihah 3634 — Story of Imam Mahdi

Sayyiduna Jabir (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "When ‘Isa ibn Maryam (peace be upon him) descends, the leader of the Muslims, Mahdi, will say to him: 'Come and lead the prayer.' He will say: 'No, you yourselves are leaders and amirs of one another; this is an honor and dignity from Allah for this Ummah.'"
