I took money from a debt to trade with it, so what is the ruling on the zakah of it?

Question:
I heard the Shaykh say: The questioner took money from his brother as a debt to trade with it. He took money from his brother as a debt to trade with it, so does he owe zakah, or does he pay off the debt that is on him?

Answer:
If you took the money as a loan to deal with it and trade, you owe its zakah, and the debt does not prevent it. The debt does not prevent zakah; this is the correct view. So if you have, for example, ten thousand and you owe people five thousand, or more or less, you have to pay zakah on what you have, and the debt does not prevent it. But if you pay off the debt before the completion of the lunar year, there is no harm. If you have ten thousand and owe five thousand, and you pay it off from the ten before the lunar year is complete, you pay zakah on the remaining five. But if the lunar year passes and you have not paid zakah, you pay zakah on the entire amount, and the debt does not prevent it.
