Zakah due on money remaining from

Q: I have a sum of money that I bought merchandise with and added it to other trade goods that are also kept for commercial purposes. The lunar year has not passed regarding all the commercial items, how should I pay Zakah (obligatory charity) on these merchandises? (Part No. 9; Page No. 317)

A: If you buy such goods for commercial purposes in addition to other goods you had before, then you are obliged to pay Zakah if they reach the Nisab (the minimum amount on which Zakah is due) either by itself or by addition to other money, and a full lunar year passes from the date of your intention to use it for trade. Thus, estimate the value of your merchandise after the elapse of one lunar year and pay 2.5% as Zakah i.e., for every one hundred riyals, two riyals and half are due as Zakah. Likewise, for every one thousand riyals, 25 riyals and so on.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
