When the Prophet Jesus (as) returns, there will be no relatives or anyone else to recognize him. Not a single person will be able to say he recognizes him. Nobody will be able to say they are related. Nobody can say he is his brother. That will be one of the pieces of evidence allowing us to recognize the Prophet Jesus (as).
It is a miraculous state of affairs that there are people who espouse bloodshed and anarchy when they could be living in peace, love and beauty. Everyone thinks people should desire peace and love for all, and that this will make them happy. But that does not apply to many people. They want conflict and bloodshed, and even make a football match an excuse for spilling blood.
