He ran 13:35.43. Justyn Knight, who impressively made the final competing on his first outdoor senior national team for Canada, finished ninth in 13:39.15 as both Canadians finished in the top-10.
Farah finished in a time of 13:33.22, with Edris's time clocked at 13:32.79.
And they took aim at America's Kenyan-born bronze medallist Richard Chelimo for making Farah's trademark "Mobot" gesture and then running his hand across his throat as the 5,000m runners lined up before their race.
A lover of sports who seeks to tell the African story in an African way. "It didn't really hit home until I crossed the line and I had a couple of minutes to myself and realised this is it", said an emotional Farah before he took one last lap of honour around this track, which was the launchpad to his impending legendary status at London 2012. "Nothing was guaranteed but I took that chance".
He overtook Australian frontrunner Patrick Tiernan with 600m to go and, as the pace wound up, assumed his favourite position at the front of the race.
It looked at one point as if Farah may not even make the podium but he bravely challenged up the inside in the straight and managed to overhaul two of his rivals. "I don't think there was any more I could have done".
"They had the game plan: one of them was going to sacrifice themselves".
The Observer remarked that those who had come in their thousands with their faces painted with "Go Mo!" and banners with "Run Farah Run" were to be left disappointed. I gave it all.
"I knew I was going to beat Mo Farah", the new gold medalist said. So many times, you guys have been unfair to me.
After success on the European stage, Farah was gearing up for another World Championships and decided that he would move to Portland, Oregon full-time and start work with a new coach, Alberto Salazar.
"You can write what you like but I'm a clean athlete... and I sleep well at night, loving my kids, hugging my kids, showing (them) what's right".
"I am the next champion". "I did the Mobot out of respect as well for him".
