I heard a man reciting a verse (of the Holy Qur'an) but I had heard the Prophet (ﷺ) reciting it differently.
So, I caught hold of the man by the hand and took him to Allah's Messenger (ﷺ) who said, "Both of you are
right." Shu`ba, the sub-narrator said, "I think he said to them, "Don't differ, for the nations before you
differed and perished (because of their differences). "
