Mutual functions.

Allah created human beings in such a way that they are dependent on each other and depend on each other for help. It is never possible for everyone alone to get what they need. Someone may be entitled to something that meets someone else's needs and someone may be dependent on something that is available to someone else. In doing so, Allah awakened in them the idea of ​​adapting to the system of exchanging goods and profits through buying and selling. In this way all the needs of the people are fulfilled and in this way the human life is strengthened. This is not only a matter of mutual respect of individuals, but also nations and states can continue to exchange the fruits of mutual welfare and production.

When the Prophet (peace be upon him) was sent, various kinds of buying and selling and mutual transactions were going on in the Arab society. Then the favorable arrangements and practices of the Islamic Shari'ah were maintained, it was declared permissible, and all that was contrary to the Shari'ah was declared haram and forbidden. This prohibition is divided into several stages. For example, to assist and co-operate in committing any sin, deception, plunder of high value and profit, and oppression of either party to the treaty.

Using and benefiting from prohibited and haram products is also haram and cave level work. For this reason it is haraam to buy or sell it or to do its business. Pigs, alcohol, forbidden food and drink, idols, crosses, statues, etc. are considered at this stage. If the buying and selling and trading of these things were allowed, then these acts of sin would be widespread.

People were motivated to do that, it was made easy to do, people were taken to it. That is why people were encouraged. But since buying and selling these things and acquiring them has been forbidden. As a result, people can survive. Right now people can't look at these things, or there can be no reason to remember them. People have been asked to keep away from contact with these things.
