Seeking a fitting end to his matchless long-distance racing career before moving to marathon running, the 34-year-old Briton's bid for a fifth straight global 10,000/5000m double was scuppered as he had to settle for the silver.
Farah, who had won the 10,000m last Friday to open the championships with a bang, said he couldn't have given it more but added he had proved that it was possible to break up the Ethiopian and Kenya hegemony over the distance races.
France's Olympic silver medallist Kevin Mayer won gold in the world decathlon.
Admitting he had been outmanoeuvred, Farah said: "I got boxed in early on - it doesn't normally happen - but I got boxed in early and couldn't get out".
"I don't think there was any more I could have done".
Claiming to have been exhausted after his 10,000m efforts and 5,000m heats, he added: "Tactically, I was trying to cover every move".
"They had the game plan: one of them was going to sacrifice themselves".
Farah was less than a second back in 13:33.22, the Kenyan-born America Paul Chelimo winning bronze in 13:33.30. The better man won.
Mo Farah's aura of invincibility after six years of unrelenting success was finally cracked in his very last major track race on Saturday as he lost his world 5,000 meters title to Ethiopia's Muktar Edris.
With nine laps to go Farah's fellow Brit Andrew Butchart briefly led with the pace slow as Edris and Cyrus Rutto made the moves to go up with Farah.
As the group went through the 3,000m mark Australian Patrick Tiernan was the one who made a decision to change the pace and he opened up a little gap between Chelimo, Farah and the rest of the pack.
Into the last 800m however and they ate Tiernan up, though the truth is Farah never looked entirely comfortable: they hit the bell in 12:40.17, and Farah was chasing all the way down the backstretch, unable to get himself in front when he either wanted to or needed to.
