Thomas Jefferson owned a copy of the Qur'an, which was the second edition of a 1734 translation by George Sale, a two-volume set published in London in 1764. This set was sold to the Library of Congress in 1815, and rebound by the Library in 1918. The daybook of the Virginia Gazette records the purchase of this edition by Jefferson in Williamsburg in 1765.1 There are no other known records of Jefferson reacquiring this work, suggesting perhaps that it survived the fire at Jefferson's family home, Shadwell, in 1770.
In 2007, Jefferson's copy of the Qur'an was used by United States Representative Keith Ellison (D-MN) to take his oath of office.
