Finally, here's the link to the clip of me (14 minutes, 41 seconds) from April 23, 2010on "Bill Bennett's 'Morning in America'" with (former) Senator Rick Santorum--I'm discussing Mahdism, particularly in Iran:

Recently, on PeaceTV (an Urdu and English TV station broadcasting from Mumbai and run by Zakir Naik, an Indian Islamist recently denied entry to to the U.K), a man claimed to be the Mahdi:

What's interesting about this episode is, yet again, a wanna-be Mahdi crops up even in a staunchly Sunni venue (Naik and his TV outlet are on record as opposing Shi`ism, contra his claims of inter-Muslim tolerance).  Also, the willingness by even such an off-kilter Muslim to make a public claim to the Mahdiyah indicates that the traditions about the Mahdi's coming are being studied and internalized--preparing the ground for more serious, and potentially dangerous, Mahdist aspirations in the future. One does wonder, however, what happened to this poor deluded man after the cameras stopped rolling.
More disturbing than this mutamahdi is the "sister at the back," shown at 2:46 (before the clip ends at 2:49), clad in what appears to be a dusty brown, oh-so-stylish, burkha and backed by sartorially-similiar Muslimas.   Of course, once the real Mahdi comes, that garb will likely be mandatory for all women. 
Update:
This video has been posted to a site called "Pakistan Defence Forum" (http://www.defence.pk/forums/general-images-multimedia/63234-man-claims-mahdi-live-peace-tv.html).  There are a number of comments on it--most notably this one:
"It seems false Mahdi [sic] are popping [sic] all over. Another reason to keep blasphemy laws and apply them to these clowns."

For some reason, although I've had a Twitter account for over a year, I've never thought to let folks on here know. Well, if you are a Tweety-bird,  you can find me as Occidentaljihad.

More than it has in the past, if a story on the Islamic Republic of Iran's Islamic unity website from this week is accurate:
"The Grand Sheikh of Al-Azhar said that Sunnis and Shias are two wings of the Islamic Ummah adding that over last fourteen centuries since the emergence of Islam, these two schools of thought have never fought one another. The senior Sunni scholar added that the current conflicts between Shias and Suunis  are a plot to bring ignite sectarian strife."  Furthermore, "Al Azhar is now prioritizing the issue of proximity of Islamic Schools of thought adding that this premier Sunni institution welcomes Shia students from Iran and other parts of the Islamic world."
(Link to this story at Iran's World Forum for Proximity of Islamic Schools of Thought is here: http://www.taghrib.ir/english/index.php?option=com_content&view=article&id=241:al-azhar-rejects-wahhabi-call-to-denounce-recognition-of-shia-islam&catid=38:2009-08-31-05-02-22&Itemid=66 .)
Observations:
1) The Grand Shaykh of Sunni Islam's most prestigious religious institution, in Cairo, needs to bone up on his Islamic history if he thinks Sunnis and Shi`is "have never fought one another."  Husayn was not killed in 680 AD by Americans, or even by Christians.  The Sunni Abbasid and Sevener Shi`i Fatimid Empires (based in Baghdad and Cairo, respectively) fought for the better part of two centuries.  The Sunni Ottoman and Shi`i Safavid (Iranian) Empires were at war almost continually for a quarter-century.  Shi`is and Sunnis have been killing one another in Iraq since Saddam went down in 2003.  Like too many Muslims (and Muslim apologists), al-Tayyib resides in a Platonic world of Islamic comity and unity rather than in the real, historical world of inter-Muslim (and extra-Muslim) violence.
2) The self-congratulation in Qom (and its satellite, Tehran) over this alleged welcoming of Twelver  (and other) Shi`i students to Cairo should be taken with a shaker of salt; two months ago al-Arabiya reported that Shaykh al-Tayyib said the following:
"Egypt's top cleric stressed that he will be very vigilant and will foil any political agenda adopted by any Shiite student studying in Egypt, as he doesn't want the issue to turn into a 'trap' for young Sunni Muslims to attract them to the Shiite [sic] doctrine, which could later turn into a Shiite nucleus then a center that could be followed by fighting that has nothing to do with Islam and its beliefs at all" (http://www.alarabiya.net/articles/2010/04/02/104756.html). 
Note that last phrase, "that has nothing to do with Islam and its beliefs at all."  It's unclear whether it refers back to "fighting" or to Shi`ism: if the former, then the head of al-Azhar is either, again, ignorant of the martial tradition in Islam or flat-out lying; if the latter, then the Twelver Shi`i holy center of Qom is deluding itself that the Sunni seat of learning in Cairo is extending an ecumenical olive branch.
(And a tip of the hat to to that herertical Montanist Tertullian for this blog post title.)

According to the Kuwaiti newspaper al-Siyassa, Usama bin Ladin and Ayman al-Zawahiri have been living in northeastern Iran (in Khorasan) for five years, thanks to the mediation of Lebanese Hizbullah: http://www.memrijttm.org/content/en/report.htm?report=4338&param=GJN
At the risk of not just beating but exhuming a dead horse--I've been making this argument for years.  And note that a number of hadiths (including Sunni ones) say that the Mahdi will come out of Khorasan.
