Engage in transactions that are fair and just for all parties involved.

The hadith narrated by Anas bin Malik states that the Prophet Muhammad forbade the practice of Shighar in Islam. Shighar is an exchange or barter between two parties, where one party gives something to another without receiving anything of equal value in return. This type of transaction is prohibited according to Islamic teachings as it goes against the principles of fairness and justice. It also encourages people to take advantage of each other and can lead to exploitation and injustice. Therefore, Muslims are encouraged to avoid such practices and instead engage in transactions that are fair and just for all parties involved.
