AFC Women's Asian Cup
The win secured Palestine a third-place finish with three points while Tajikistan completed their campaign empty handed.
Having both been eliminated following two defeats, Palestine and Tajikistan came into the tie with pride at stake.
Palestine came close in the 18th minute with Naomi Philips flashing her shot from distance just wide, while Tajikistan wasted a chance in the 37th minute after Saiyora Saidova played a long ball to Marjona Saidova, who miscued her attempt inside the box.
Both sides continued to waste chances as the score remained goalless in a tepid first half.
Palestine, however, upped their tempo after the break and broke the deadlock in the 49th minute.
Nadine Mohammad orchestrated the move when she drove the ball down the middle before slipping a well-timed pass to Dalia Asadhalim, who beat the offside trap to score past an advancing Farahnoz Kholdorova.
Mohammad played a pivotal role again in the 69th minute when she intercepted a loose ball before setting up the attack through Nour Youssef, who threaded the ball for Asadhalim to finish with ease.
Youssef then showed her skill when she dribbled past two Tajikistan players at the edge of the box before finishing with a lob over Kholdorova in the 74th minute as Palestine ended their campaign on a high note.
