What should I do regarding the sale of shares in Sahara Petrochemical Company, and is the money resulting from their sale lawful or unlawful, after I learned that a group of scholars have prohibited them?

If the company's shares are unlawful, it is not permissible to sell or buy them, and they must be returned to the company. If the law does not permit this, then do not sell them, as the object of sale is not permissible according to Sharia.

Regarding profits, if the company's activity is lawful, take the profits and dispose of a percentage equivalent to the company's funds placed in usurious banks. However, if its activity is unlawful, it is not permissible for you to take the profits; rather, you should receive them and distribute them for the benefit of Muslims.
