The Pakistan cricketers have crushed England, the world's top-ranked test team, by 10 wickets to win the first test inside three days in Dubai.
Having conceded a 146-run first-innings lead, England collapsed to 160 all out in their second innings.
Pakistani opener Mohammad Hafeez alone scored the 15 runs his team needed to complete the formality of victory.
England were dismissed for 192 in their first innings and in the second, Jonathan Trott with 49, was the lone top-five batsman to reach double figures.
The second test starts in Abu Dhabi mid next week.
