Narrated Ibn 'Abbas: When the Messenger of Allah ﷺ came to Medina, they were paying one, two and three years in advance for fruits, so he said: Those who pay in advance for anything, must do for a specified measure and weight with a specified time fixed.
The Prophet's teachings on this matter emphasize the importance of being honest and fair in all transactions, especially those involving money or goods. It also encourages people to be mindful of their spending habits so as not to waste money unnecessarily by overpaying or buying more than what is needed at once.
Overall, this hadith serves as an important reminder to always be mindful when making purchases so that everyone involved can benefit from it fairly and honestly without any misunderstandings or disputes arising later on down the line.
