Thawbān, the Prophet's freed slave, reported that the Prophet (may Allah's peace and blessings be upon him) said: "Two groups of my Ummah Allah shall protect from the Fire: a group that invades India and a group that will be with ‘Īsa ibn Maryam (peace be upon both of them."
Explanation
Two groups from the Ummah of Prophet Muhammad (may Allah's peace and blessings be upon him) will be saved from Hellfire: a group that invades the lands of India and fights the disbelievers in the cause of Allah, and a group that will be with ‘Īsa ibn Maryam when he comes down to earth at the end of the time, after the appearance of the Anti-Christ, whom ‘Īsa (peace be upon him) will kill.
