Coming to the match, batting first, Pakistan managed to score 282 in their first innings after losing five wickets for just 57 runs.
The former England captain may have scored nearly 8,000 worldwide runs and 18 Test centuries, but he says Abbas is the type of bowler that would make him "poop his pants".
It was Abbas, 28, who destroyed Australia with a haul of 17 wickets in the series - becoming the first Pakistani fast bowler to take ten wickets in a Test since Mohammad Asif did so against Sri Lanka at Kandy in 2006.
Abbas completed match figures of 10-95 after backing up his first-inning 5-44 with 5-62 second time around as Australia - shorn of first-Test hero Usman Khawaja due to a knee injury - were skittled for 164 chasing a notional 538 for victory.
The tour went from bad to worse for the Marsh brothers with the bat, with Mitchell lasting just the five balls in sync with his brother's six.
Two balls later, captain Tim Paine was out without scoring while trying to leave a ball that nipped back enough and knocked over the off stump.
Legspinner Yasir Shah ran through the tailenders with 3-45, finishing off the match by having Jon Holland caught in the slips on 3.
This is Pakistan's biggest win (by runs) in Test, previous biggest was 356 runs in 2014.
Imad has been out of the Pakistan limited-overs squad since past year due to a knee problem and was also overlooked for the Asia Cup last month after failing a fitness test.
Pakistan stand-in captain Asad Shafiq outsmarted Finch's tactic of standing well outside his crease while facing Abbas, by making Rizwan stand close to the stumps, forcing the batsman inside the crease.
Marnus Labuschagne and Mitchell Starc, however, denied them a wicket for 16 overs as they added 67 runs for the sixth wicket.
Sarfraz also missed a ton, gone for 81 as Labuschagne claimed his fifth wicket for the Test and seventh for the series to top Australia's bowling averages.
