Sunnah of The Prophet ﷺ & his successors

The Messenger of Allāh ﷺ said:

فَعَلَيْكُمْ بِسُنَّتِي وَسُنَّةِ الْخُلَفَاءِ الْمَهْدِيِّينَ الرَّاشِدِينَ تَمَسَّكُوا بِهَا وَعَضُّوا عَلَيْهَا بِالنَّوَاجِذِ وَإِيَّاكُمْ وَمُحْدَثَاتِ الأُمُورِ فَإِنَّ كُلَّ مُحْدَثَةٍ بِدْعَةٌ وَكُلَّ بِدْعَةٍ ضَلاَلَةٌ

You must stick to my Sunnah and the Sunnah of my rightly guided successors, hold to it and stick fast to it. Beware of newly invented matters, for verily, every newly invented matter is an innovation, and all innovation is misguidance.
