paragraph_text: Al-Mu'tadid was the son of al-Muwaffaq, who was the regent and effective ruler of the Abbasid state during the reign of his brother, Caliph al-Mu'tamid. As a prince, the future al-Mu'tadid served under his father during various military campaigns, most notably in the suppression of the Zanj Rebellion, in which he played a major role. When al-Muwaffaq died in June 891 al-Mu'tadid succeeded him as regent. He quickly sidelined his cousin and heir-apparent al-Mufawwad, and when al-Mu'tamid died in October 892, he succeeded to the throne. Like his father, al-Mu'tadid's power depended on his close relations with the army. These were first forged during the campaigns against the Zanj and were reinforced in later expeditions which the Caliph led in person: al-Mu'tadid would prove to be the most militarily active of all Abbasid caliphs. Through his energy and ability, he succeeded in restoring to the Abbasid state some of the power and provinces it had lost during the turmoil of the previous decades.

In response, the military raised its level of alertness while the Burmese Muslim Association issued a statement saying Muslims would not tolerate any threat to their motherland.

The Persians became furious and determined to recover Al-Hirah from the Muslims. Rostam Farrokhzād, a famous Sasanian general, sent some of his relatives from the Ispahbudhan family along with some Persian generals. Khalid bin Walid had already left for Syria so Musana had to fight alone. Umar sent Abu Ubaid with reinforcements. In the battle that followed the Persians were defeated.

In this remote location, the ruler again turned to the Portuguese.

paragraph_text: Muhammad also ordered another siege on the Banu Qurayza during the Invasion of Banu Qurayza, because according to Muslim tradition he had been ordered to do so by the angel Gabriel. Al-Waqidi claims Muhammad had a treaty with the tribe which was torn apart. Stillman and Watt deny the authenticity of al-Waqidi. Al-Waqidi has been frequently criticized by Muslim writers, who claim that he is unreliable. 600-900 members of the Banu Qurayza were beheaded after they surrendered (according to Tabari and Ibn Hisham). Another source says all Males and 1 woman beheaded (according to Sunni Hadith). Two Muslims were killed

paragraph_text: Since he took power in 1995, Hamad bin Khalifa al-Thani believed Qatar could find security only by transforming itself from a Saudi appendage to a rival of Saudi Arabia. Saudi Arabia withdrew its ambassador to Doha from 2002 to 2008 to try to pressure Qatar to curb its individualistic tendencies. This approach broadly failed. The Arab Spring left a power vacuum which both Saudi Arabia and Qatar sought to fill, with Qatar being supportive of the revolutionary wave and Saudi Arabia opposing it; since both states are allies of the United States, they avoid direct conflict with one another. Qatar has had differences with other Arab governments on a number of issues: it broadcasts Al Jazeera; it is accused of maintaining good relations with Iran; and it has supported the Muslim Brotherhood in the past. Qatar has been accused of sponsoring terrorism. Some countries have faulted Qatar for funding rebel groups in Syria, including al-Qaeda’s affiliate in Syria, the al-Nusra Front, although the Saudis have done the same. Qatar has allowed the Afghan Taliban to set up a political office inside the country. Qatar is a close ally of the United States, hosting the largest American base in the Middle East, Al Udeid Air Base.

paragraph_text: In astronomy, Muḥammad ibn Jābir al-Ḥarrānī al-Battānī improved the precision of the measurement of the precession of the Earth's axis. The corrections made to the geocentric model by al-Battani, Averroes, Nasir al-Din al-Tusi, Mu'ayyad al-Din al-'Urdi and Ibn al-Shatir were later incorporated into the Copernican heliocentric model. Heliocentric theories were also discussed by several other Muslim astronomers such as Al-Biruni, Al-Sijzi, Qotb al-Din Shirazi, and Najm al-Dīn al-Qazwīnī al-Kātibī. The astrolabe, though originally developed by the Greeks, was perfected by Islamic astronomers and engineers, and was subsequently brought to Europe.
