'Adi b. Hatim reported: that a person recited a sermon before the Apostle of Allah (may peace be upon him) thus: He who obeys Allah and His Apostle, he in fact follows the right path, and he who disobeys both of them, he goes astray. Upon this the Messenger of Allah (may peace be upon him) said: What a bad speaker you are; say: He who disobeys Allah and His Apostle. Ibn Numair added: He in fact went astray.
