If the owner of a piece of land intends to sell it when he needs the proceeds, is zakah due on it?

Question:
He says: Honorable Shaykh, may Allah grant you success. A person was granted a piece of land and sold it after seven years. It is known that he did not intend to trade in it or seek the highest price, but his intention was, for example, that he needed money to buy a car or to get married, so he sold it for whatever price. The question is: how is the zakah in this case?

Answer:
It is due from the time he resolved to sell it. The lunar year begins from the time he resolved to sell it; before that, there is no zakah on it. Yes.
