Khan said he wanted to win the trophy for the people back home, who have been facing plenty of problems in recent times.
"We want to make people back home happy. Winning the title will mean a lot to them and that will inspire us in the final. One more game and the World Cup will be ours,"The News quoted Khan, as saying.
Pakistan has reached the final of the T20 World Championship for the second consecutive time. However, it crashed to a five run defeat against India in the inaugural T20 World tournament in South Africa in 2007.
Pakistan will now face either Sri Lanka or the West Indies in the final at Lord's on Sunday.
Khan said he is not bothered over which team he would be playing against in the final, but admitted that both the teams would be tough to beat, as Sri Lanka have been undefeated in the tournament, and the West Indies has lost only one match on their road to the semi-finals.
"We will keep track of both Sri Lanka and the West Indies. They are tough sides but we are not worried who we play. We will just go out and put our best effort, like we did against South Africa," Khan said.
Earlier, a brilliant all-round performance by Shahid Afridi helped Pakistan defeat South Africa by seven runs to knock them out of the Championship.
Afridi banged the Proteas bowlers all around the park during his stupendous innings of 51 of just 34 balls.
Later, he grabbed 2-16 with his patent fast leg-spin to help defend a modest target of 149.
South Africa could manage only 142 runs in their quota of 20 overs with five wickets remaining, and thus were unable to strip the 'chokers' tag from themselves. (ANI)
