Zakah on land sold before the completion of the lunar year and land held as trade goods

Question:
Honorable Shaykh, may Allah grant you success. A man says: He sold a piece of land he owned before the lunar year (hawl) had completed. Is there zakah on it? And if this land is among trade goods and has been held for several years, how does he pay its zakah?

Answer:
He pays zakah on it every year based on its value, paying zakah on its value for each year as long as he intends to sell it. He pays one-quarter of one-tenth. If he sells it before the lunar year is completed and spends its value before the year is complete, then there is nothing due on it. However, if its value, or some of it, remains with him until the lunar year is completed, he pays zakah on the value or the remainder.
