[Machine] The Messenger of Allah ﷺ delivered a speech, praised Allah and thanked Him, then he said: "Verily, the best guidance is the guidance of Muhammad ﷺ , and the worst of matters are those newly invented (in religion), and every innovation is misguidance."  

الدارمي:٢١٢أَخْبَرَنَا مُحَمَّدُ بْنُ أَحْمَدَ بْنِ أَبِي خَلَفٍ حَدَّثَنَا يَحْيَى بْنُ سُلَيْمٍ حَدَّثَنِي جَعْفَرُ بْنُ مُحَمَّدٍ عَنْ أَبِيهِ عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ الْأَنْصَارِيِّ قَالَ

خَطَبَنَا رَسُولُ اللَّهِ ﷺ فَحَمِدَ اللَّهَ وَأَثْنَى عَلَيْهِ ثُمَّ قَالَ «إِنَّ أَفْضَلَ الْهَدْيِ هَدْيُ مُحَمَّدٍ ﷺ وَشَرَّ الْأُمُورِ مُحْدَثَاتُهَا وَكُلَّ بِدْعَةٍ ضَلَالَةٌ»

"إِنَّ أَفضَلَ الحديثِ كتابُ اللَّه، وأحسنَ الْهدِى هَدْىُ محمد، وشَرِّ الأُمُورِ مُحدثَاتُها وكلَّ بدعة ضلالةٌ، ومن تركَ مالًا فلأَهلِهِ، ومن ترك دينًا أَو ضِيَاعًا فَعلَىَّ ".
