Jofra Archer led the way as fired-up England put their T20 World Cup campaign firmly on track.
The Sussex paceman took 3-12 as Oman were bowled out for just 47.
England then chased down the runs in a record 19 deliveries.
In the process, they wiped out their net run-rate deficit to ensure they will go second if they win tomorrow’s clash with Namibia.
Pace pair Mark Wood and Archer returning matching figures in an innings which lasted only 13.2 overs.
With the race on to chase the runs in 5.2 overs and move ahead of Scotland’s rate of 2.164 in the process, Phil Salt set the tone by launching the first two balls of the reply hard over long-on for six.
He was cleaned up swinging at the third and Will Jacks followed but Jos Buttler lashed 24 not out off just eight balls and Jonny Bairstow crunched both deliveries he faced for four to win it with 101 balls unused.
No batting side has ever finished a game quicker at this level and England’s net run-rate was dragged from -1.8 to 3.081 in the process.
Archer kicked off the procession of wickets at the Sir Andy Roberts End.
Pratik Athavale and captain Aqib Ilyas were both unsettled by his length and lift, trying to get on top of the bounce but only succeeding in feeding low catches that were snapped up by Salt and Jacks.
Archer should have had a third when Moeen Ali grassed an ankle-high chance at slip.
Shoaib was last man out, top-edging Archer into Buttler’s gloves.
England skipper Buttler said: “I thought the tone was set by the bowlers - take early wickets and restrict them. They bowled brilliantly, they bowled a good line and length.”
