The Ruling on the Zakah of the Monthly Salary

Question:
May Allah reward you. These are questions that have come in regarding the zakah on the monthly salary: how is it to be done? The monthly salary and the income that increases are well known.

Answer:
The rule is that there is no zakah on wealth until a lunar year has passed over it. This is the rule. However, for the one who pays zakah every year on a sum that is difficult for him to calculate, because the arrangement of these monthly salaries is such that calculating the total for each one is difficult for him, is it best, in the opinion of our scholars, that he designates a month of the year, such as Ramadan, and then pays zakah on what has accumulated with him, whether a lunar year has passed over it or not, until the same month of the following year? He makes this month the season for paying the zakah on the wealth he has accumulated, whether a lunar year has passed over it or not, because this is easier for him.
