What is the ruling on commercial trading on the "Big Option" website, where the amount deposited in the account continuously increases, and is the profit resulting from this investment unlawful, especially after converting to an Islamic account to ensure there are no usurious increments?

The true nature of the website's transactions is not clear to us; therefore, we cannot issue a ruling on it. Furthermore, its claim of being Islamic holds no weight unless its actual transactions are indeed so. If the participant pays money and receives a guaranteed fixed profit, then this is impermissible, just as binary options are forbidden. Therefore, it is necessary to ascertain the true nature of the website's transactions and whether they comply with Sharia (definition) regulations.
