Be honest in your dealings with others .

This hadith discusses the permissibility of exchanging goods and services for money. It was narrated by Ibn 'Umar that he used to sell camels at Al-Baqi and exchange Dinars for Dirhams. He asked the Prophet if this was permissible, and the Prophet said that it was allowed as long as all transactions were completed on that same day, unless there was unfinished business between buyer and seller. This hadith teaches us that it is acceptable to exchange goods or services for money in a fair manner, so long as both parties are satisfied with their end of the deal. However, it also reminds us not to take advantage of others in our dealings; we should always strive to be honest in our transactions with others so that everyone involved can benefit from them equally.
