There have been quite a few people who have tried to impersonate him, but most have been imposters. The only time we'll find out is when the events that were prophesised by our beloved Prophet Muhammad (peace be upon him) will occur, and the imposters have all been caught out because not all the events occured when they labelled themselves the mahdi.


However, you can download a lecture which is regarding that if you want, with all the evidences insha'Allaah (God willing.) and the prophecies.




Peace.
