Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) says that the Messenger of Allah (peace and blessings be upon him) said: "A group of my Ummah will continue to fight for the truth and will remain dominant until near the Day of Resurrection." Then he (peace and blessings be upon him) said: "Isa bin Maryam will descend, and the leader of the Muslims will say: 'Come and lead us in prayer.' Isa will say: 'No, some of you are leaders over others; Allah Almighty has honoured this Ummah.'"
