[Machine] The Prophet Muhammad ﷺ advised them one day after the morning prayer. Tears flowed and hearts trembled from it. A man said, "O Messenger of Allah, this is like a farewell sermon. What do you advise us?" He said, "I advise you to fear Allah and to have good listening and obedience, even if a black Abyssinian slave is appointed over you. Verily, whoever among you lives after me will see much disagreement, so beware of newly invented matters, for they are misguidance. And adhere to my Sunnah and the Sunnah of the rightly guided caliphs after me, and hold onto it with your molars."
أَنَّ رَسُولَ اللهِ ﷺ وَعَظَهُمْ يَوْمًا مَوْعِظَةً بَعْدَ صَلَاةِ الْغَدَاةِ فَذَرَفَتْ مِنْهَا الْعُيُونُ وَوَجِلَتْ مِنْهَا الْقُلُوبُ فَقَالَ رَجُلٌ يَا رَسُولَ اللهِ إِنَّ هَذِهِ مَوْعِظَةُ مُوَدَّعٍ فَمَا تَعْهَدْ إِلَيْنَا؟ قَالَ «أُوصِيكُمْ بِتَقْوَى اللهِ وَالسَّمْعِ وَالطَّاعَةِ وَإِنْ عَبْدًا حَبَشِيًّا فَإِنَّهُ مَنْ يَعِشْ مِنْكُمْ بَعْدِي فَسَيَرَى اخْتِلَافًا كَثِيرًا فَإِيَّاكُمْ وَمُحْدَثَاتِ الْأُمُورِ فَإِنَّهَا ضَلَالَةٌ وَعَلَيْكُمْ بِسُنَّتِي وَسُنَّةِ الْخُلَفَاءِ الرَّاشِدِينَ مِنْ بَعْدِي عُضْوًا عَلَيْهَا بِالنَّوَاجِذِ»
