Be honest with your measurements or weights so as not to cheat anyone else out of what is rightfully theirs .

This hadith is about fairness when it comes to weights and measures. It was narrated by Ibn 'Abbas that when the Prophet (ﷺ) came to Al-Madinah, he found that the people there were not being fair with their measurements or weights. They would give less than what was due or take more than what was due from others. Allah then revealed a verse which warned those who did this kind of thing - called Mutaffifun - that they would be punished for it if they continued doing so. After this revelation, the people of Al-Madinah became much fairer with their measurements and weights. This hadith teaches us an important lesson about fairness; we should always be honest with our measurements or weights so as not to cheat anyone else out of what is rightfully theirs.
