Is subscribing to shares offered by stock markets permissible or impermissible?

Shares represent a portion of a company's capital and are divided into two types: shares in prohibited institutions or those whose earnings are unlawful, such as usurious banks. These are unlawful based on the Almighty's saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." The second type is shares in permissible institutions, such as legitimate trade and industrial companies. These are permissible, provided there is no harm or excessive ignorance, because their profit comes from lawful earnings.
