Q: The city remained in the hands of Christian troops until 1102, when the Almoravids retook the city and restored the Muslim religion. Although the self-styled 'Emperor of All Spain', Alfonso VI of León and Castile, drove them from the city, he was not strong enough to hold it. The Christians set it afire before abandoning it, and the Almoravid Masdali took possession on 5 May 1109. The event was commemorated in a poem by Ibn Khafaja in which he thanked Yusuf ibn Tashfin for the city's liberation.The declining power of the Almoravids coincided with the rise of a new dynasty in North Africa, the Almohads, who seized control of the peninsula from the year 1145, although their entry into Valencia was deterred by Ibn Mardanis, King of Valencia and Murcia until 1171, at which time the city finally fell to the North Africans. The two Muslim dynasties would rule Valencia for more than a century.

A: In what year did Christian troops lose control of Valencia?

Q: Studies by Nathaniel Kleitman in 1938 and by Derk-Jan Dijk and Charles Czeisler in the 1990s put human subjects on enforced 28-hour sleep–wake cycles, in constant dim light and with other time cues suppressed, for over a month. Because normal people cannot entrain to a 28-hour day in dim light if at all,[citation needed] this is referred to as a forced desynchrony protocol. Sleep and wake episodes are uncoupled from the endogenous circadian period of about 24.18 hours and researchers are allowed to assess the effects of circadian phase on aspects of sleep and wakefulness including sleep latency and other functions.[page needed]

A: What time cycle did studies in 1938 and 1990s use on humans?
****
Q: Many Islamic anti-Masonic arguments are closely tied to both antisemitism and Anti-Zionism, though other criticisms are made such as linking Freemasonry to al-Masih ad-Dajjal (the false Messiah). Some Muslim anti-Masons argue that Freemasonry promotes the interests of the Jews around the world and that one of its aims is to destroy the Al-Aqsa Mosque in order to rebuild the Temple of Solomon in Jerusalem. In article 28 of its Covenant, Hamas states that Freemasonry, Rotary, and other similar groups "work in the interest of Zionism and according to its instructions ..."

A:
What do Islamic anti-masonics link Freemasonry to?
