What is the ruling on the shares of the telecommunications company that I bought years ago, and how should I deal with them as zakat if they are permissible, or dispose of them if they are unlawful?

It is permissible to purchase shares in a telecommunications company if it does not engage in forbidden activities or invest in an interest-bearing bank. The shares are subject to zakat by combining them with cash and trade goods if they reach the minimum threshold (nisab) and a full year (hawl) has passed. However, if the company engages in forbidden activities or invests in usury, it is not permissible to purchase its shares. The contract must be rescinded if possible; otherwise, you should retain them and dispose of the illicit profits by spending them on charitable causes.
