Al-Firyābī narrated to us, saying: Muhammad ibn Ubayd ibn Hassāb narrated to us, saying: Hammād ibn Zayd narrated to us, saying: Abū Imrān al-Jawnī narrated to us, saying: Abdullāh ibn Rabāh al-Ansārī wrote to me: “I heard Abdullāh ibn Amr say: ‘One day, I went early to the Messenger of Allah—may Allah bless him and grant him peace—when he heard two men disagreeing over a verse of the Quran. The Messenger of Allah—may Allah bless him and grant him peace—came out to us with anger visible on his face and said: “Those before you were destroyed only because of their disagreement concerning the Book.”’”
