According to Jabir b. ʿAbd Allah (ra), Allah’s Messenger (saw) used to say in his sermon after the statement of the profession of faith, “Verily, the most truthful speech is the Book of Allah Almighty, the best guidance is the guidance of Muhammad.” (Ibn Hanbal, III, 320)
According to Abu Hurayra (ra), Allah’s Messenger (saw) said, “Whoever obeys me obeys Allah, and whoever disobeys me disobeys Allah.…” (Muslim, al-ʿImara, 33)
According to Abu Hurayra (ra), the Prophet (saw) said, “Whatever I have commanded you, do it, and whatever I have forbidden you, refrain from it.” (Ibn Maja, al-Sunna, 1)
Al-ʿIrbad b. Sariya (ra) reported, “One day after the fajr prayer, the Messenger of Allah (saw) exhorted us to the extent that the eyes wept and the hearts shuddered with fear. A man said, ‘O Messenger of Allah! Indeed, this is a farewell exhortation. So what do you command us?’ He said, ‘I enjoin you to fear Allah, and to hear and obey even if it be an Abyssinian slave, for those of you who live after me will see great disagreement. You must then follow my sunna and that of the rightly-guided caliphs. Hold to it and stick fast to it. Avoid novelties, for every novelty is an innovation, and every innovation is an error.’”
(al-Tirmidhi, al-ʿIlm, 16; Abu Da’ud, al-Sunna, 5)
According to Imam Malik, Allah’s Messenger (saw) said, “I have left two things with you. As long as you hold to them, you will not go the wrong way. They are the Book of Allah and the sunna of His Prophet.”
(Muwattaʾ, al-Qadar, 3)
