Getting the reward of an action if one made waseelah through that action

There is hadith in 'Fazail A'mal' about three persons who got trapped in a cave. In order to escape from that they gave wasila to Allah Ta'ala of one of their good deeds each. Then Allah Ta'ala made way for them to escape.

I want to ask: If a person is in some sort of trouble and if he asks Allah Ta'ala in the above mentioned manner, then the good deed which he gave wasila of, will the "ajar" (reward) of that deed get finished or will he get that deed's "ajar" (reward) in the afterlife also?
