Buying in cash to benefit from the discount while evading taxes

Question:
Allah sent you this question from Europe. The questioner says: We have companies in Italy. This question is from Europe. The questioner says: We have companies in Italy. If I buy goods from them, they give you the price, then a specific price, then they offer a discount if the value of the goods is paid in cash. They give you a percentage reduction, and perhaps more, depending on the agreement. And they benefit from this by evading taxes. Is it permissible for me to pay in cash and benefit from this discount?

Answer:
Yes, there is no doubt that the sale is divided into two types: immediate and deferred, and the immediate is less than the deferred. One does not defer except for an increase. Allah (Exalted and Majestic is He) says: The default in sale is that it is lawful, and the value differs between cash and deferred payment. This is a known matter. It is a known matter that cash differs from deferred payment; deferred is more. And you have the choice to buy immediately or buy on credit. If they condition that if you buy one item you must buy another, that is two sales, two sales. And if you buy another, they prefer that, that is not permissible, two sales, two sales. Yes.
