Muhammad Ali, one of the most famous athletes in American history and a convert to Islam in the 1960s, returned to the public spotlight Wednesday night to say that political leaders have a responsibility to foster understanding about his religion.
His comments came after Donald J. Trump, the leading Republican presidential candidate, stoked anti-Muslim sentiment in the United States by, among other things, suggesting that foreign Muslims be barred from traveling to the country. Mr. Trump has also questioned President Obama’s affirmation that Muslim Americans are some of the nation’s sports heroes.
