Background: Hasan ibn Ali ibn Muhammad (c. 846 - 874) was the 11th Imam of Twelver Shia Islam, after his father Ali al-Hadi. He was also called Abu Muhammad and Ibn al-Ridha. Because Samarra, the city where he lived, was a garrison town, he is generally known as al-Askari (Askar is the word for military in Arabic). Al-Askari married Narjis Khatun and was kept under house arrest or in prison for most of his life, until, according to some Shia sources, he was poisoned at the age of 28 on the orders of the Abbasid caliph Al-Mu'tamid and was buried in Samarra.
Context: Various legends relate to al-Askari's wife, Narjis Khatun (the mother of the twelfth Imam, Muhammad al-Mahdi). It is said that al-Askari's father, Ali al-Hadi, wrote a letter in the script of Rum; put it in a red purse, with 220 Dinars; and gave it to his friend Bashar ibn Sulaiman. The letter instructed him to go to Baghdad, to a ferry place on the river where the boats from Syria were unloaded, and female slaves were sold. Bashar was told to look out for a shipowner named Amr ibn Yazid, who had a slave girl who would call out in the language of Rum: "Even if you have wealth and the glory of Solomon the son of David, I can never have affection for you, so take care lest you waste your money." And that if a buyer approached her, she would say "Cursed be the man who unveils my eyebrow!" Her owner would then protest, "But what recourse do I have I; I am compelled to sell you?" "You will then hear the slave answer", said the Imam, "Why this hast, let me choose my purchaser, that my heart may accept him in confidence and gratitude."  Bashar gave the letter, as he was instructed, to the slave girl; who read it, and was not able to keep from crying afterward. Then she said to Amr ibn Yezid, "Sell me to the writer of this letter, for if you refuse I will surely kill myself." "I therefore talked over the price with Amr until we agreed on the 220 Dinars my master had given me," said Bashar. On her way to Samarra, the slave girl would kiss the letter and rub it to her face and body; and when asked by Bashar why she did so despite not knowing the writer of the letter, she said, "May the offspring of the Prophet dispel your doubts!" Later on, however, she gave a full description of the dream she had had, and how she had escaped from her father's palace. A lengthier version of this story is recorded in Donaldson's book, along with further discussion on the authenticity of this story.  Some Shia sources have recorded her as being a "Roman (i.e. Byzantine) princess" who pretended to be a slave so that she might travel from her kingdom to Arabia. Mohammad Ali Amir-Moezzi, in the Encyclopedia of Iranica, suggests that the last version is "undoubtedly legendary and hagiographic".
Question: How long were they married?
Answer: 

Background: William Patrick Corgan Jr. (born March 17, 1967) is an American musician, songwriter, producer, poet, and professional wrestling magnate. He is best known as the lead singer, primary songwriter, guitarist, and sole permanent member of The Smashing Pumpkins. Formed by Corgan and guitarist James Iha in Chicago, Illinois, in 1988, the band quickly gained steam with the addition of bassist D'arcy Wretzky and drummer Jimmy Chamberlin. Strong album sales and large-scale tours propelled the band's increasing fame in the 1990s until their break-up in 2000.
Context: Following a brief stint touring with New Order in the summer , Corgan reunited with Chamberlin to form the band Zwan with Corgan's old friend Matt Sweeney in late 2001. According to Neil Strauss of New York Times, during his few live performances with the band, Corgan says "is still a work in progress." The lineup was completed with guitarist David Pajo and bassist Paz Lenchantin. The band had two distinct incarnations, the primary approach being an upbeat rock band with a three-guitar-driven sound, the second, a folk and gospel inspired acoustic side with live strings. The quintet performed throughout 2002, and their debut album, Mary Star of the Sea, was released in early 2003 to generally positive reviews. In the midst of their supporting tour for the album, mounting conflict between Corgan and Chamberlin, and the other band members led to the cancellation of the rest of the tour as the band entered an apparent hiatus, formally announcing a breakup in September 2003.  In 2004 Corgan began writing revealing autobiographical posts on his website and his MySpace page, blaming Iha for the breakup of the Smashing Pumpkins, calling Wretzky "a mean spirited drug addict," and criticizing his former Zwan bandmates' fixation with "indie cred" and calling them "filthy", opportunistic, and selfish.  On September 17, 2003, Billy first presented his poetry at the Art Institute of Chicago's Rubloff Auditorium. In late 2004, Corgan published Blinking with Fists, a book of poetry. Despite mixed reviews, the book debuted on the New York Times Best Seller list. Around this time, he began posting autobiographical writings online under the title The Confessions of Billy Corgan.  Also in 2004, he began a solo music career, landing on an electronic/shoegaze/alternative rock sound for his first solo album, TheFutureEmbrace, co-produced and arranged by Bon Harris of Nitzer Ebb. Released on June 21, 2005, through Reprise Records, it garnered mixed reviews from the press and only sold 69,000 copies. Corgan toured behind his solo album with a touring band that included Linda Strawberry, Brian Liesegang and Matt Walker in 2005. This tour was not as extensive as previous Smashing Pumpkins or Zwan tours. Prior to recording TheFutureEmbrace, Corgan had recorded some 72 songs inspired by Chicago history for the largely acoustic ChicagoSongs project, which have yet to be released.
