Example of Trade Profit

Question : Trade profit: A person bought a piece of land for one hundred thousand.

Answer : During the lunar year, he sold it for one hundred and fifty thousand. We say that if the first lunar year of its purchase has completed, then zakah is due on the entire amount, on the one hundred and fifty thousand, because the fifty thousand is profit. Thus, trade profit follows the original capital regarding the lunar year and the nisab. The offspring of grazing livestock follows the original capital regarding the lunar year and the nisab. What is gained from other sources follows the original capital regarding the nisab, but not regarding the lunar year.
