"The 'scientific method,' as it is understood today, was first developed by Muslim scientists" like Ibn al-Haytham and Al-Biruni, along with numerous other Muslim scientists.

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.

According to journalist Arnold J. Toynbee c. 300 Muslims were killed during April–July 1921.
