Problem: 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".

Problem: Background: Slayer is an American thrash metal band from Huntington Park, California. The band was formed in 1981 by vocalist/bassist Tom Araya and guitarists Kerry King and Jeff Hanneman. Slayer's fast and aggressive musical style made them one of the founding "big four" bands of thrash metal, alongside Metallica, Megadeth and Anthrax. Slayer's current lineup comprises King, Araya, drummer Paul Bostaph and guitarist Gary Holt.
Context: Following the success of Hell Awaits, Slayer was offered a recording contract with Russell Simmons and Rick Rubin's newly founded Def Jam Records, a largely hip hop-based label. The band accepted and with an experienced producer and major label recording budget, the band underwent a sonic makeover for their third album Reign in Blood resulting in shorter, faster songs with clearer production. Gone were the complex arrangements and long songs featured on Hell Awaits, ditched in favor of stripped down, hardcore punk influenced song structures. Def Jam's distributor, Columbia Records, refused to release the album due to the song "Angel of Death" which detailed Holocaust concentration camps and the human experiments conducted by Nazi physician Josef Mengele. The album was distributed by Geffen Records on October 7, 1986. However, due to the controversy, Reign in Blood did not appear on Geffen Records' release schedule. Although the album received virtually no radio airplay, it became the band's first to enter the Billboard 200, debuting at number 94, and the band's first album certified gold in the United States. In October 1986, Slayer embarked on the Reign in Pain world tour, with Overkill in the US, and Malice in Europe. The band was added as the opening act on W.A.S.P.'s US tour, but just one month in, drummer Lombardo left the band: "I wasn't making any money. I figured if we were gonna be doing this professionally, on a major label, I wanted my rent and utilities paid." To continue with the tour, Slayer enlisted Tony Scaglione of Whiplash. However, Lombardo was convinced by his wife to return in 1987. At the insistence of Rubin, Slayer recorded a cover version of Iron Butterfly's "In-A-Gadda-Da-Vida" for the film Less Than Zero. Although the band was not happy with the final product, Hanneman deeming it "a poor representation of Slayer" and King labeling it "a hunk of shit," it was one of their first songs to garner radio airplay.
