"Reuters reporter Ross Colvin reported that the speech would attempt to mend the United States' relations with the Muslim world, which he wrote were "severely damaged" during the presidency of George W. Bush.. . . The president opened his speech seeking a common ground between Muslims and the United States. He quoted from the Quran, 'Be conscious of God and always speak the truth.' Obama described Muslim contributions to Western civilization, citing the founding of algebra, the development of navigational tools, the invention of the fountain pen, and the influence of Islamic architecture. He described his own personal experiences with Islam, including having Muslim family members, growing up in Indonesia, a majority-Muslim country and hearing 'the call of the azaan', and working 'in Chicago communities where many found dignity and peace in their Muslim faith'".
