What is the ruling on advertising a competition that involves sending text messages at a high price to win a car, knowing that refusing the advertisement will harm other agencies and may lead the company to resort to legal action?

It is not permissible to participate in or advertise competitions where the cost of the message is higher than usual, because this is considered prohibited gambling, as the participant pays an extra amount to obtain a prize, and this falls under the definition of gambling. It is not permissible to cooperate in sin and aggression, and whoever advertises these competitions is a partner in sin.
