A group of my Ummah will fight for the truth until near the day of judgment when Jesus, the son of Marry, will descend, and the leader of them will ask him to lead the prayer, but Jesus declines, saying: “No, Verily, among you Allah has made leaders for others and He has bestowed his bounty upon them.
