question #3 Sahih al-Bukhari 5062, Book 66, Hadith 87 : What lesson can be learned from the Prophet’s response to differing Quranic recitations?

That he heard a man reciting a Quranic Verse which he had heard the Prophet (ﷺ) reciting in a different way. So he took that man to the Prophet (and told him the story). The Prophet (ﷺ) said, “Both of you are reciting in a correct way, so carry on reciting.” The Prophet (ﷺ) further added, “The nations which were before you were destroyed (by Allah) because they differed.”
