Dude/or girl, see the speech marks ive put up in your post....I think youve answered your own question.! If the Prophet SAW has already told us what his name is going to be why would we accept someone who has a different name? I mean if we are accepting all the other predictions why are not accepting the one with the name?
Can i ask where the yuj and Majooj have appeared? you obviously mean "on a different level". So please explain!
Ok doke. Suppose out of 100 forecasts about Imam Mehdi AS, 99 or 98 are met.. except for one or two prediction.. (say hes not from where he was thought to be from).. will you really reject Him?
PS: Prophet Muhammad (Peace and blessings of Allah be upon Him)'s names are also Hamid, Mehmood, Aziz, Mansoor, Mubashar , Ahmad.
