Ibn 'Umar (Allah be pleased with them) reported that they were beaten during the lifetime of Allah's Messenger ﷺ if they had bought foodgrains in bulk and then sold them in the spot without shifting them (to some other place).
This hadith also teaches us an important lesson about honesty and integrity when trading goods. We should always be honest with our customers and make sure that we are not taking advantage of them by overcharging or undercharging for our products. We should also ensure that we are providing quality products at fair prices so that everyone benefits from our transactions.
