Barack Hussein Obama II (; born August 4 1961) is the junior United States Senator from Illinois. He is the presumptive nominee of the Democratic Party in the 2008 presidential election, and the first African American to be a major party's presumptive nominee for President of the United States.

A graduate of Columbia University and Harvard Law School, Obama worked as a community organizer and practiced as a civil rights attorney before serving in the Illinois Senate from 1997 to 2004. He also taught constitutional law at the University of Chicago Law School from 1992 to 2004. Following an unsuccessful bid for a seat in the U.S. House of Representatives in 2000, he announced his campaign for the U.S. Senate in January 2003. After winning a landslide primary victory in March 2004, Obama delivered the keynote address at the Democratic National Convention in July 2004. He was elected to the Senate in November 2004 with 70% of the vote.

As a member of the Democratic minority in the 109th Congress, he cosponsored legislation to control conventional weapons and to promote greater public accountability in the use of federal funds. He also made official trips to Eastern Europe, the Middle East, and Africa. In the current 110th Congress, he has sponsored legislation regarding lobbying and electoral fraud, climate change, nuclear terrorism, and care for returned U.S. military personnel. Since announcing his presidential campaign in February 2007, Obama has emphasized withdrawing American troops from Iraq, increasing energy independence, decreasing the influence of lobbyists, and promoting universal health care as top national priorities.

Jihad ( ), an Islamic term, is a religious duty of Muslims. In Arabic, Jihad means "strive" or "struggle". Jihad appears frequently in the Qur'an and common usage as the idiomatic expression "striving in the way of Allah (al-jihad fi sabil Allah)"., Jihad, p.571 , Jihad, p.419 A person engaged in jihad is called a mujahid, the plural is mujahideen.

A minority among the Sunni scholars sometimes refer to this duty as the sixth pillar of Islam, though it occupies no such official status.John Esposito(2005), Islam: The Straight Path, pp.93 In Twelver Shi'a Islam, however, Jihad is one of the 10 Practices of the Religion.

According to scholar John Esposito, Jihad requires Muslims to "struggle in the way of God" or "to struggle to improve one's self and/or society."Esposito (2003), p.93 pg 174-176 Jihad is directed against Satan's inducements, aspects of one's own self, or against a visible enemy. pg. 17 The four major categories of jihad that are recognized are Jihad against one's own self (Jihad al-Nafs), Jihad of the tongue (Jihad al-lisan), Jihad of the hand (Jihad al-yad), and Jihad of the sword (Jihad as-sayf). Islamic jurisprudence focuses on regulating the conditions and practice of Jihad as-sayf, the only form of warfare permissible under Islamic law, and thus the term Jihad is usually used in fiqh manuals in reference to military combat.
