And the 27-year-old favourite made no mistake at the Arena Birmingham, streaking around the blue track for an unprecedented eighth Ethiopian victory in the last nine world indoor 3000m events, Kenya's Hellen Obiri the only blot back in 2012.
Genzebe Dibaba won her third consecutive gold in the women's 3000m competition at the 2018 IAAF World Indoor Championships in Birmingham, England on Thursday, March 1st, 2018.
Muir went into this event as the double European indoor champion but her global record against tougher opposition had previously been less convincing.
Laura Muir won a silver medal in the women's 3,000m after Eilidh Doyle earlier claimed bronze in the women's 400m at the World Indoor Championships in Birmingham.
Liz's daughter Eilish was Muir's team-mate here and, like Muir, is doubling up at 1500m. "This time yesterday I was in a taxi halfway down the M6".More news: UFC 222 breakdown, betting odds and picks
With a grimace beginning to show on her face as the clock showed 8:14.61 at the bell, Dibaba had amassed a safe -but by no means unassailable- lead of roughly twelve metres on Hassan and Muir, but in their chase for the silver medal, the gap to Dibaba began to narrow.
Genzebe Dibaba of Ethiopia became the third athlete to win the women's 3000m title at the IAAF World Indoor Championships on at least three occasions in an exciting climax to the first day which had a sparse but enthusiastic home crowd cheering the narrow but growing possibility of a home victor in Laura Muir on the last lap.
Dibaba proved that she is an indoor performer when she had to work round that last lap as Hassan and Muir battled for the minor medals, but in reality neither were able to challenge the Ethiopian who always looked to have an extra gear. Tomorrow she's back in the first round of the 1500m.
Giles, who initially finished fourth, was upgraded to third after Drew Windle was disqualified for an apparent obstruction while Doyle - in the final after being upgraded in the semi-final following disqualifications - took her first individual world medal. With 1000m left they all pushed very hard and at that moment I had to go and win the race.
"I knew even if I got ahead I could carry on my running smoothly", Doyle told BBC Sport.More news: Million Penguins 'Supercolony' Earlier Detected From Space, Discovered on Antarctica's Danger Islands
"I'm surprised at how well I balance veterinary and track". I had to dig in on that last lap. I just tried to take my time and not panic.
"I feel I'm improving every year and getting stronger".
"I had to send a few emails saying: 'I've got a big competition coming up, is it OK if I have a couple of days?' They were fine about it".
Dibaba crossed the finish-line in 8:45.05, a finishing time made respectable courtesy of a scintillating final kilometer of 2:37.43. So to come out with a medal in that situation is fantastic.

Obiri was a distant fourth, four seconds behind Muir, with Houlihan using her kick for fifth as Klosterhalfen faded to seventh.
