A sum from the revenue of the clinic, that reaches the Nisab by itself or when added to other money, and a Hawl has passed on it

Q: I am a Saudi physician who owns a comprehensive family clinic. I want to pay the Zakah (obligatory charity) due on my property to the Department of Zakah in Makkah Al-Mukarramah. Since my capital is about (150,000) one hundred and fifty thousand riyals, the amount of the Zakah due on my capital is ( 3,750) three thousand, seven hundred and fifty riyals. Is there any other Zakah due from me? It is worth mentioning that my income from the clinic is spent on myself and my family, and nothing of it remains for a Hawl (one lunar year calculated from the time a property reaches the minimum amount upon which Zakah is due) to pass on it.Please clarify what Zakah is due from me according to Shari`ah (Islamic law) to be paid to the Department of Zakah.

A: If you have a sum from the revenue of this clinic, that reaches the Nisab (the minimum amount on which Zakah is due) by itself or when added to other money, and a Hawl has passed on it since the time you received it, it is Wajib (obligatory) on you to pay Zakah on it. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
