Question: What was the population of the Hejaz region during The Battle of Badr? Passage 1:Gresham was born to William Gresham (1802–1834) and his wife Sarah Davis. William had been elected a Colonel in the militia of Indiana. He was a member of the Whig Party and was elected Sheriff of Harrison County, Indiana. On January 26, 1834, William was fatally stabbed while assisting in the arrest of Levi Sipes, a so-called "desperado". His paternal grandparents were George Gresham (born 1776) and Mary Pennington.

He was released from service upon reaching adulthood. He later served in the Continental Army. He married Sarah O'Neal. Lawrence followed his son to Kentucky and Indiana well into his old age.
 Passage 2:The Battle of Badr (), fought on Tuesday, 13 March 624 CE (17 Ramadan, 2 AH in the Islamic calendar) in the Hejaz region of western Arabia (present-day Saudi Arabia), was a key battle in the early days of Islam and a turning point in Muhammad's struggle with his opponents among the Quraish in Mecca. The battle has been passed down in Islamic history as a decisive victory attributable to divine intervention, or by secular sources to the strategic genius of Muhammad. It is one of the few battles specifically mentioned in the Quran. All knowledge of the battle at Badr comes from traditional Islamic accounts, both hadiths and biographies of Muhammad, recorded in written form some time after the battle. There is little evidence outside of these of the battle. There are no descriptions of the battle prior to the 9th century.
