Salam to all the brothers and sisters
thank you for your topic Orion, yes many claim to be prophets, many claim to be mahdies, BUT, Many liers doesn't mean No right person!
in the era of prophet mohammed (s), there were many liers who claimed to be prophets like Sujjah, Musailamah AL-Kathab,,,etc but that doesn't mean that the prophet is also wrong!
well you asked many questions about Imam Ahmad Al-Hassan and it's nice to show the manners of Ahlul Bait in this website, not swearing I guess.
Imam Ahmad is the messenger and guradian from Imam Al-Mahdy (s), he is from Basrah and appeared year 1999 in Najaf Al-Ashraf where he met Imam Al-Mahdy personally, he has many books, bayanat and recordings by his voice.
there is so much to say, please access the website for more info:
Ansar Al Imam Al Mahdy
it is absolutely wrong to say there is no messengers for Imam Al-mahdy before he appear as you said, even the maraji3 said there is messengers, because Ahlul bait said that, so
watch out Allah bless you from denying the narrations of our honorable Imams. The narrations about the messenger will be mentioned from authentic Shia Books.
i had also noticed that some of you still don't believe there is a will from Prophet Mohammed mentioned in the Shia authentic books, this is wrong actually, the will is there since hundreds of years and it is mentioned in the books, so why should we say it's not there and close the subject!
here is the will:
It was narrated about Abu Abdullah

about his forefathers about Amir Al Mo’mineen (Ali PBUH) that he said: The Messenger of Allah

said: During the night of his death: “O Father of Al Hassan, bring me a leaf and a paper”, and he dictated his will until he came to a position where he said "O Ali, there will be twelve Imams and after them there will be twelve Mahdi’s. You, O Ali, are the first of the twelve Imams, and the speech kept on going until he said: Let Al-Hassan

hand the will to his son M O H A M M A D, the preserved of Mohammad’s Family

, and those are the twelve Imams. Then there will be twelve Mahdi’s after them. then when the day of death comes to him, let him hand the will over to his son, the first of the close ones, he has three names, one like mine and my Father’s: Abdollah (Servant of God), Ahmad and the third name is The Mahdi (the guided) and he is the first Believer.” Bihar Al Anwar (Oceans of Lights), chapter 53 page 147, and Ghaybat Al Tousi (Occultation by Al Tousi) page 150. And Ghayat Al Maram chapter 2 page 241.
Ahmad is the first believer in Imam Al-Mahdy in the era of his holy emergence.
hence, you can't disbelieve in anything new "to you" that comes across, search and be patient that Allah is with you and will not mislead you!
moreover, Imam Ahmad is the yamani mentioned by Imam Al-Baqir (s)
In a Narration about Imam Al Baqir

(There is no banner better than that of the banner of Yamani, it is the banner of faith and dedication, because he calls to your possessor, so if the Yamani comes out, selling weapons to people or any Muslim becomes prohibited, and if the Yamani appears, stand up to him, because he’s banner is the banner of faith, and its prohibited for any Muslim to turn away from him, and who ever turns away from him, then he’s from the people of hell, because he calls to the truth and to the right path).
Here we have the right to ask:
If this flag is of such important importance, and who ever ignores it goes to hell, and the case is clear by standing up to him, then why not set any details??
We do not know the name of the Yamani or the Yamani’s description or the Yamani’s place of origin, or anything, but if we turn against him we will enter the fire of hell.
Here are the books that talk about the Imam Mahdi, where you find narrations and find many explanations about the characters of the era of emergence, except the character of the Yamani, as it is indistinct. Even though it is the most important, why is this silence on this character? Does god and his Messenger and Ahlu-albait (the family of the prophet ) want to mislead us, which they will never do (god forbid), then why is that?
Moreover, if any person claims that he is the owner of this character, we will certainly not accept him and we will ask him about the evidence.
For us it is easy, and our desires agree with us to say to whomever claims something great is lying, and we convince ourselves that his decisive argument of God was incomplete and we don’t commit ourselves to stand by him, but it is compulsory on the Yamani himself to bring us something to convince us that he is the Yamani.
(In the book of sheikh Al-Noamani published in Beirut the year 1983 page 220)
From Malik Al-Juhani he said: I said to Abu Ja'far

: “we describe the man of this matter with the aspects that no one of the people has ever had.”
He said: “No, By Allah, it is not so. It is he himself, who will argue with you about that and will invite you to it.”
And I think that the reason for the dimness of this character are at least three main reasons:
-1.so it wouldn’t be easy to claim on each claiming liar, and thus, cause disruption between people.
-2.To protect its owner from his many enemies in the era of emergence.
-3. To trial and test people to distinguish the believers and infidels, and this is the way of God with every owner of a Divine matter.
And at this point, of course many of your honors are asking, yes, so what did your “caller” come with to prove that he is the Yamani, and here is the answer:
He came in and argued the evidence (narrations of Muhammad

) and showed who this character is, whom we are obliged to stand by and obey before the appearance of Imam Mahdi,

:
He showed us what’s the meaning of Yamani, and

said:
You must first know that Mecca is from Tohama and Tohama is from Yemen. This means that Mohammad and his family (PBUT) are all Yamania. Mohammad

is a Yamani, Ali

is a Yamani and Imam Mahdi

is a Yamani and the 12 Mahdieen are Yamania and the first Mahdi is a Yamani as well. This is what the first active (working) scholars (May god have mercy on)knew: (then, there has succeeded them a posterity who have give up As-Salat (the prayers) [i.e. made their Salat (prayers) to be lost, either by not offering them or by not offering them perfectly or by not offering them in their proper fix time]and have followed lusts so they will be thrown in hell.)(Mariam-59)
now we will discuss the Yamany narration:
First) It’s prohibited for any Muslim to turn away from him, and who ever turns away from him, then he’s from the people of hell, and this means that the Yamani (is a holder of a divine mandate), as a person won’t be a decisive argument of God on people, to a point that whoever turns against him goes to hell, even if they prayed and fasted, except if he was from ((The successors of Allah on his land)).
Second) (And because he calls to the truth and to the right path). The call to the truth and the right path, or the straight path means: (That this person does not make a mistake which results in making the people do wrong, or takes them out of the straight path). In other words, He is an infallible and texts have been written about his infallibility. In this sense, this limitation and/or constraint comes in handy to define the character of The Yamani. As for the presumption of any other meaning to these words (because he calls to the truth and to the right path) then this makes the words of them (PBUTA) useless, and there won’t be a constraint and/or no limit to the character of the Yamani, and god forbid that they )PBUTA) would do such a thing.
The outcome from what came in the first and second:
The Yamani) is a decisive argument from the arguments of God on his land and is infallible with text to admit his infallibility.
Then who are the owners of the divine mandate of God? They are the prophets and messengers and guardians.
And who are the guardians after the Messenger of Allah

?
The answer is, they are the twelve Imams and the twelve Mahdi’s... they Are mentioned by the Messenger of Allah

on The night of misfortune After Omar said what he said, and the messenger of Allah expelled him from his house. He dictated his will, to Ali

and it was witnessed by Abu Thar and Salman and Mokdad.
Mahdi11: let me answer what you wrote, His real name is Ahmad and his surname is Al-Hassan, the way we have Imam Ali (Al-Redha), Imam Jaáfar (Al-Sadiq), etc.
let me tell you that cursing is absolutely forbidden for us in the our rooms in paltalk and other programs, it is an order from Imam Ahmad Al-Hassan. (i dnt know if what you wrote is a lie!)
Taqleed is unlawful to anyone on earth only to al-masoomen, because they know halal and haram and they will never lead us to astray, this thing is known since long time Mahdi11, taqleed was brought around year 1920. whereas, before Imam Ahmad Al-Hassan, we have the narrations of our beloved Imams and they have completed the religion, don't you read their narrations?
read this: æÇáÕÇÏÞ (Ú) íÞæá ( ÅÐÇ ÎÑÌ ÇáÞÇÆã íäÊÞã ãä Ãåá ÇáÝÊæì ÈãÇ áÇ íÚáãæÇ ÝÊÚÓÇð áåã æáÃÊÈÇÚåã Ãæó ßÇä ÇáÏíä äÇÞÕÇð ÝÊããæå Ãã ßÇä Èå ÚæÌÇð ÝÞæãæå ¡ ....) . ÅáÒÇã ÇáäÇÕÈ Ì2 Õ200 .
it says: Imam Al-Sadiq (s) said: (if the Qai'm egresses, he takes revenge from the holders of Fatwa with what they knew not, so woe to them and to their followers! was the religion incomplete so they complete it? or it had curvature so they straighten it?,....) ilzam alnasib, part2 , pg200
what is fabricated? do you enjoy telling people you lie just because you desire? please pay attention to what is happening around.
