The match was reduced to 28 overs a side due to rain and Preston Mommsen captaining the side in place of Kyle Coetzer decided to bat on winning the toss.
Michael Leask was the only change for Scotland coming in for Coetzer.
Matthew Cross was promoted up the order to open with Calum MacLeod and the two batsmen took the attack to the UAE from the off hitting the ball to all parts as they scored at over a run a ball.
UAE captain Khurram Khan mixed his bowlers about as they struggled to make the breakthrough. It eventually came in the eighteenth over when Rohan Mustafa the seventh bowler to be used beat the defence of cross to bowl him for 88, which had came from 60 balls and his innings included 10 fours and 3 sixes.
MacLeod continued to dominate with the bat and he reached a well deserved century before he was the third wicket to fall with the score on 227, having contributed 113 to the total.
The lower order with licence to attack saw Scotland finish on 265 for 6 from their 28 over allocation.
Naveed and Mustafa with three wickets a piece were the pick of a UAE attack that struggled to contain the rampant openers.
On the resumption of play Scotland made an early breakthrough when Wardlaw had Salman Faris caught by Majid Haq with the score on five and 31 runs later he struck again to dismiss Amjad Ali when he had him caught by Freddie Coleman.
Khurram Khan and Shaiman Anwar then consolidated for the UAE and put on a further74 runs before Haq enticed Anwar to give Berrington a catch.
While Khan was at the crease the UAE were in with a chance of victory but when MacLeod, the seventh bowler used by Scotland, was introduced into the attack he got him caught by Berrington for 87.
A defiant 41 by keeper Swapnil Patil saw the UAE edge closer to their target but when he was the last man out they were 53 runs short to give Scotland a well deserved victory.
Man of the Match MacLeod followed up his heroics with the bat with two wickets and Haq and Wardlaw snapped up three wickets each.
Scotland will now travel to Christchurch where they will play Canada in their final Group A match on Thursday (23 January) while UAE will remain in Queenstown to play Hong Kong on the same day.
Scotland will be hoping that UAE come out on top which will then mean that the three teams (Hong Kong, Scotland and UAE) would then progress to the Super Sixes with two points each.
