Does our company sell one of its products and give a mobile phone as a gift to whoever buys a certain quantity from it?

Question:
Honorable Shaykh, may Allah grant you success. He says: Our company sells one of its products, and it carried out an advertisement stating that if any customer buys a certain quantity of our products, we will give him a mobile phone as a gift. Is this action permissible?

Answer:
No, this is not permissible, because it is consuming wealth unjustly, and because it encourages buying even if one has no need to buy, just for the sake of the gift. And because it harms other shops and draws customers to the one who gives prizes, leaving the shops that do not give prizes. This is harm to the Muslims: either they do what he does, or people avoid this action. This action is not permissible. Yes.
