From Sahih Muslim (Hadith 2007):
Jabir reported that the Messenger of Allah (ﷺ), while delivering the sermon' to the people, praised Allah, and lauded Him for what He deserves, and would then say:He whom Allah guides aright, there is none to mislead him, and he who is led astray, there is none to guide him (aright), and the best of the talk is embodied in the Book of Allah. And the rest of the hadith is the same
