Narrated to me 'Amr ibn Muhammad ibn Bukayr ibn Muhammad al-Naqid, narrated to us Isma'il ibn 'Ulayyah, from Sa'id al-Jurayri, narrated to us 'Abd al-Rahman ibn Abi Bakrah, from his father, who said: We were with the Messenger of Allah, peace and blessings be upon him, and he said: "Shall I not inform you of the greatest of the major sins?" — three times — "Associating partners with Allah, and disobedience to parents, and bearing false witness" — or "uttering false speech." And the Messenger of Allah, peace and blessings be upon him, had been reclining, then he sat up, and he kept repeating it until we said, "Would that he had fallen silent."
