What is the ruling on purchasing air conditioners from the bank?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: I approached one of the banks to purchase air conditioners. They do not own them, and they do not have a warehouse, but they said, "If you want us to bring them, we will bring them for you without you paying anything, and then you have the option after they are brought." The question is: Should I buy them from them or not?

Answer:
The Prophet (peace and blessings be upon him) said: So if the seller does not have the goods, it is not permissible for you to agree with him. It is not permissible for you to agree to buy them when they are not present, and then he goes... And their saying, "We do not bind you," or something like that, is a lie. This is a lie. They do not go to buy them unless they are deceiving you, fixing the price against you, and taking money from you. They take money from you, then they go to buy something, and they sit with it. They go to buy it only out of greed, and they fix the price and take your signature and take a deposit from you.
And their saying, "We do not bind you," is a form of lying and deception. The conclusion is that it is not permissible to go to anyone who does not have the goods, whether banks or others. Do not go to anyone who does not have the goods.
