Wait for merchandise before purchasing it .

This hadith teaches us the importance of fair trading practices. The Prophet Muhammad ﷺ has instructed us not to buy or sell goods in a way that harms others. We should wait for the merchandise to be brought down to the market before we purchase it, instead of competing with each other for it. This ensures fairness and justice in trading, as everyone has an equal chance at buying or selling goods without any unfair advantage over another person. Furthermore, this hadith also encourages us to practice patience and self-control when dealing with business matters, as rushing into decisions can lead to undesirable outcomes.
