What is the ruling on buying and trading shares of a telecommunications company whose stock symbol contains the number 700, knowing that scholars have prohibited this number?

For the permissibility of dealing in shares with companies, two conditions must be met: that the company's core business activity is Islamically permissible, and that it does not deposit a portion of its shares in interest-based (usurious) banks. As for the number 700, if its use is in the context of a lottery, then it is forbidden (haram), and consequently, it is forbidden to deal with a company that engages in such practices.
