Is it permissible to buy and sell pure shares that deal with usurious banks, with rapid daily speculation, and is this considered usury, and is trading them during work forbidden, and are they entirely pure?

It is permissible to trade in the pure shares of companies engaged in lawful activities that do not deal with usury. Shares represent a common stake in the company's assets, and trading in them is not considered money for money but rather goods for money. It is advisable to disregard excessive scrupulousness in this matter if one's soul is not at ease with it, knowing that the majority of scholars permit trading in them. However, it is not permissible for an employee to trade in shares during official working hours, as an employee's time belongs to their employer. The five daily prayers, meal times, and answering the call of nature are exceptions to this.
