Narrated Salim: that his father said".I saw those, who used to buy foodstuff without measuring or weighing in the life time of the Prophet ﷺ being punished if they sold it before carrying it to their own houses".
This hadith also teaches us that we should be careful with our dealings and not be careless with our measurements or weights when buying or selling goods as this could lead us astray from justice and fairness which are essential values in Islam. We must always strive to be honest and accurate in all our dealings so that we can earn Allah’s pleasure and reward on the Day of Judgment.
