The only solution

The leader of a prison (I am sorry if my words aren't perfect but I translate these riddles from Hungarian to English) was in big trouble and he went to the tricky and wise Hodzsa.
- Oh, wise Hodzsa! I am in big trouble. - that's how he started. - You are the only person who can help me.
- What has happened? - asked Hodzsa.
- Just one little thing. Our Lord (God gives him long life) has visited our prison and he had a little conversation with an inmate and he got to like him. "How long will he have to be here" - asked our Lord. "Till death." - I answered.
The Lord started to nod and he told me to half the captivity of that inmate. But how could I do such a thing? Who knows when he would die?
- I know the solution. - said Hodzsa with a big smile on his face.
