'Abdullah b. 'Umar reported: I went to Allaah's Messenger (sallAllaahu alayhi wa sallam) in the morning and he heard the voice of two persons who had an argumenta- tion with each other about a verse. Allaah's Prophet (sallAllaahu alayhi wa sallam) came to us (and) the (signs) of anger could be seen on his face. He said: Verily, the (peoples) before you were ruined because of their disputation in the Book.
