وَعَنْ جَابِرٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَمَّا بَعْدُ فَإِنَّ خَيْرَ الْحَدِيثِ كِتَابُ اللَّهِ وَخَيْرَ الْهَدْيِ هَدْيُ مُحَمَّدٍ وَشَرَّ الْأُمُورِ مُحْدَثَاتُهَا وَكُلَّ بِدْعَةٍ ضَلَالَةٌ» . رَوَاهُ مُسْلِمٌ

English translation

Jabir reported God’s messenger as saying, “To proceed:

The best discourse is God’s Book, the best guidance is that given by Muhammad, and the worst things are those which are novelties. Every innovation is error.” Muslim transmitted it.
