Nadeem threw an Olympic record of 92.97 metres for victory, India's defending champion Neeraj Chopra taking silver with 89.45. Grenada's Anderson Peters claimed bronze with 88.54m.
The 25-year-old took silver last year but he stamped his mark on the final early on with his winning throw coming in the second round.
The gold eluded him but with a landmark silver here, Olympic champion javelin thrower Neeraj Chopra still created history one more time, becoming only the second Indian and first male track and field athlete to win a medal in the World Championships.
