A Speakers' Corner is an area where open-air public speaking, debate, and discussion are allowed. The original and most noted is in the north-east corner of Hyde Park in London, England. Speakers here may talk on any subject, as long as the police consider their speeches lawful, although this right is not restricted to Speakers' Corner only. Contrary to popular belief, there is no immunity from the law, nor are any subjects proscribed, but in practice the police intervene only when they receive a complaint. Speakers' Corner is often held up to demonstrate freedom of speech, as anyone can turn up unannounced and talk on almost any subject, although always at the risk of being heckled by regulars.

Terrorism is the use of intentionally indiscriminate violence as a means to create terror among masses of people. With aim to create fear to achieve a financial, political, religious or ideological aim. It is used in this regard primarily to refer to violence against peacetime targets or in war against non-combatants. The terms "terrorist" and "terrorism" originated during the French Revolution of the late 18th century but gained mainstream popularity during the U.S. presidency of Ronald Reagan (1981-89) after the 1983 Beirut barracks bombings and again after the 2001 September 11 attacks. There is no commonly accepted definition of "terrorism". Being a charged term, with the connotation of something "morally wrong", it is often used, both by governments and non-state groups, to abuse or denounce opposing groups.

Early Islam or the history of Islam is believed, by most historians to have originated with Muhammad's mission in Mecca and Medina at the start of the 7th century CE. Although Muslims regard this time as a return to the original faith passed down by the Abrahamic prophets, such as Adam, Noah, Abraham, Moses, David, Solomon, and Jesus, with the submission (Islam) to the will of God. According to the traditional account, the Islamic prophet Muhammad began receiving what Muslims consider to be divine revelations in 610 CE, calling for submission to the one God, preparation for the imminent Last Judgement, and charity for the poor and needy.
