It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both), he says: The Messenger of Allah (peace and blessings be upon him) delivered a sermon to us, praised and glorified Allah as is His due, and then said: «أَمَّابَعْدُ» Verily, the truest word is the Book of Allah, and the best guidance is the guidance of Muhammad (peace and blessings be upon him), and the worst matters are those that are newly invented, and every innovation is misguidance.
