The Laws of Islam regulates people’s dealings and interactions when conducting sales and business transactions. It has laid down rules and principles clarifying essential matters, to avoid disputes among people and help them conduct lawful and smooth business transactions that are free of deceit and Laws of Islam violations. In this hadeeth, ‘Abdullah ibn ‘Umar ibn Al-Khattaab (may Allah be pleased with them) related that he saw people during the lifetime of the Messenger of Allah ﷺ buying foodstuff haphazardly, i.e., wholesale without estimation by measuring, weighing, or counting. In Islamic terminology, this type of sale is known as Bay‘ Al-Jizaaf (i.e., sale without estimation). An example of such a type of sale is when a seller sells a bowl of foodstuff without weighting it or estimating its quantity or monetary value. People used to resell the purchased commodity immediately after the purchase in their place (i.e., before carrying it to their homes or marketplaces). Therefore, the Prophet ﷺ forbade them from reselling the purchased commodities in the place of purchase, and commanded them instead to carry the purchased commodities, and take them into their possession before reselling them. He ﷺ used to appoint someone to discipline whoever did not comply with the Prophet’s ﷺcommand and resold the purchased commodities before taking possession of them. It is deduced from the hadeeth that a ruler may discipline those who engage in defective and invalid contracts. It is also inferred therefrom that it is allowable to sell foodstuff wholesale without estimation by measuring, weighing, or counting to determine its quantity. The hadeeth also highlights how the Laws of Islam preserves and regulates all aspects of people’s lives..
