📖 Al-‘Irbad Ibn Sariyah RadhiAllahu 'anhu narrated: The Messenger of Allah SallAllahu 'alaihi wa sallam prayed with us one day. Then he SallAllahu 'alaihi wa sallam faced us and delivered an eloquent sermon that brought tears to our eyes and by it shook our hearts. It was said, "O Messenger of Allah, it is as if this is a farewell sermon. What do you instruct for us?" The Prophet Muhammad SallAllahu 'alaihi wa sallam said, "I advise you to fear Allah, listen, and obey, even if an Abyssinian slave is put in charge of you. Whoever lives after me will see many conflicts. You must adhere to my Sunnah and the Sunnah of the righteous, guided successors. Hold firmly to it (to the Sunnah) as though biting with your molar teeth. Beware of newly invented matters, for every newly invented matter is an innovation (Bid'ah) and every innovation is misguidance."

📖 Abdullah Ibn Amr RadhiAllahu 'anhu narrated: Allah's noble Messenger Muhammad SallAllahu 'alaihi wa sallam said, "What comes over my nation will surely be what came over the children of Israel, step by step until if one of them fornicated with his mother, one from my nation would do the same. Verily, the children of Israel split into seventy-two sects and my nation will split into seventy-three sects. All of them will be in Hellfire except for one sect." They said, “Who are they, O Messenger of Allah?” The Prophet SallAllahu 'alaihi wa sallam said, "Those who follow my way and my companions."
