Thanks for great copy and paste but people prove to me from Muslim, Bohkari Tarmizi, Mashkak, hadith books where prophet said,"it is necessary upon you to cling on to my Sunnat and the Sunnat of the four rightly guided Caliphs". Prophet said, I leave behind me Quran and my Sunnah and other times he said I leave behind you Quran and my Ahlabat, whoever follows them will be on sarat-ul- Mustakeem.
Please don't quote self made hadith which can't be authanticated by Hadith books that majority of Muslims believe.
