What to do if the case is pending since four years

I have filed one civil case in the munisif court and the court has issued ORDER favour to me. The case is that one person has taken land sand from my land for Rs.50000. I have received the agreement deed from the opposite person. But he didn;t pay the amount. Now 4 years are gone. Still the case is pending due to impossibility to issue warrant to that person. Aournd 8 items the warrant has been issued. But the Ameen whent to the home of him and he is not able to issue the same due to the absence of the criminal. Let me know the next procedure to receive the amount. The oposite person has no land or any other property in his own name.
