Is zakat obligatory for a doctor in Iraqi Kurdistan whose monthly income with his wife is 7-8 thousand dollars, their expenses are 2000 dollars, and he has house construction installments amounting to 24 thousand dollars, and he owns a share in a private hospital valued at 20 thousand dollars that he cannot sell?

For Zakat (definition) to be obligatory, two conditions must be met: reaching the nisab (definition) (minimum threshold) and the passing of a full hawl (lunar year). Thus, saved salaries are considered Zakat-eligible wealth, and a quarter of a tenth (2.5%) of what has reached the nisab and on which a full hawl has passed—either on its own or by combining with other cash or trade goods—is to be given as Zakat. As for the share in the hospital, it is not subject to Zakat because it is not for sale. However, what it generates from the share is subject to Zakat if a full hawl passes on it and it reaches the nisab.
