Respect others and be mindful of your actions so as not to cause any harm or distress.

The Prophet Muhammad taught us that it is not ethical to compete with others in buying something that has already been bought by another person, or in proposing marriage to a woman when someone else has already proposed. This is because it can be hurtful and disrespectful towards the other person who was first involved in either of these activities. We should only do so if we have permission from the previous suitor or if they have given up on their idea. This hadith teaches us about respecting others and being mindful of our actions so as not to cause any harm or distress.
