Sheikh Ahmad al-Khalîl, professor at al-Imâm University, Qasîm Branch
The company gave you the right to buy these stocks at a fixed price whenever you wish to so that you can capitalize on changes in the market value. These options are construed in some markets to be something of value in their own right that can be bought and sold. If the stock options given to you by the company are a saleable and you intend to make business by exploiting this right that you have in them, then you have to pay Zakâh on the stock options the same as you would for any other tradable commodity.
The Zakâh amount will be due on the market value of the stock options when these options remain in your possession for one year from the time the company grants them to you.
In case you do not wish to use these stock options at all, or if stock options are not something that can be bought or sold in your country, then you do not have to pay Zakâh on them.
And Allah knows best.
