Sahih al-Bukhari, 7277
sahih

Narrated `Abdullah:

The best talk (speech) is Allah's Book 'Qur'an), and the best way is the way of Muhammad, and the worst matters are the heresies (those new things which are introduced into the religion); and whatever you have been promised will surely come to pass, and you cannot escape (it).

حَدَّثَنَا آدَمُ بْنُ أَبِي إِيَاسٍ، حَدَّثَنَا شُعْبَةُ، أَخْبَرَنَا عَمْرُو بْنُ مُرَّةَ، سَمِعْتُ مُرَّةَ الْهَمْدَانِيَّ، يَقُولُ قَالَ عَبْدُ اللَّهِ إِنَّ أَحْسَنَ الْحَدِيثِ كِتَابُ اللَّهِ، وَأَحْسَنَ الْهَدْىِ هَدْىُ مُحَمَّدٍ صلى الله عليه وسلم، وَشَرَّ الأُمُورِ مُحْدَثَاتُهَا، وَإِنَّ مَا تُوعَدُونَ لآتٍ، وَمَا أَنْتُمْ بِمُعْجِزِينَ‏.‏
