Muhammad, 31, also ducked inside the old world record, with Bol just outside the 52-second barrier.
McLaughlin's victory came after a superb tactical race which saw 2016 champion Muhammad make a flying start in the lane outside her compatriot and rival.
Muhammad led coming off the final hurdle, but McLaughlin produced a late burst of speed to claim a first gold medal.
The win came a day after the men's 400m hurdles race saw an epic duel between Karsten Warholm and Rai Benjamin, which ended with Norway's Warholm winning in another world record.
