Strive for unity and avoid differences in opinion as much as possible. Respect different opinions even if they are not your own.

This hadith speaks to the importance of unity and avoiding differences in opinion. It was narrated by Ibn Mas'ud who heard a person reciting a Quranic verse differently than how he had heard the Prophet Muhammad recite it. He took this person to the Prophet Muhammad who then said that both were correct but that they should not differ as this is what caused destruction for nations before them. This teaches us that we should strive for unity and avoid differences in opinion as much as possible so we can prevent destruction from befalling us. We must also remember that even if two people have different opinions on something, both can still be right and valid at the same time.
