Is zakah due on profits only, or also on the capital?

Question:
We have a call from our brother Sulayman from Ha'il. Please go ahead. Peace be upon you and Allah's mercy. And peace be upon you and Allah's mercy. I have a question, Honorable Shaykh. Yes. May you live long. I have an office for car and ticket sales. We entered this business with a certain amount of capital. This capital remains fixed, and the profits we make from it, we use to buy more cars. I am asking about the method of zakah and how to pay the zakah on this money. Sometimes we say Ramadan comes and we pay zakah in it, but we may not have liquid cash, and sometimes we do. Do I pay zakah on the entire amount, or only on what I currently have that I have received from the clients?

Answer:
My brother, it is obligatory for you to pay zakah on the entire amount, both the capital and the profit. Zakah is due on it. If you are unable to pay it at the present time, it remains a debt in your liability. When you are able, you must pay it in full and not deduct anything from it, because it is one of the pillars of Islam and is obligatory in your liability. Yes.
