Pakistan were set a target of 271 to win the second Test against Sri Lanka in Colombo on Sunday and draw the two-match series 1-1.
The hosts were bowled out for 282 in their second innings just before tea on the fourth day.
Skipper Angelo Mathews remained unbeaten on 43. Seamer Wahab Riaz and off-spinner Saeed Ajmal claimed three wickets each while Abdur Rehman bagged two, with two run outs to boot.
Earlier, Mahela Jayawardene signed off from test cricket with the bat with his 50th half-century as Sri Lanka extended their lead in the second innings to 222 at lunch.
The visitors picked up the experienced pair of Kumar Sangakkara and Jayawardene in the first 30 minutes of play.
Sangakkara (59) had added just five to his overnight score when he pushed forward to a delivery from Ajmal that spun and bounced and took the edge to end up in the hands of Azhar Ali at silly point.
Sangakkara’s dismissal ended a third-wicket stand of 107 with Jayawardene, the 19th occasion the pair had been involved in a century stand.
Sri Lanka won the first Test in Galle by seven wickets.
