The last sermon of the prophet witnessed by the thousands has
three versions. The versions the the references are listed below.
1) I leave with you Quran and Sunnah
2) I leave with you Quran and Ahl al-bayt
Muslim 44/4, Nu2408; ibn hanbal
4/366; darimi 23/1, nu 3319.
3) I leave you for the Quran alone you shall uphold it.
Muslim 15/19, nu 1218; ibn Majah 25/84, Abu dawud 11/56.
Because the majority of the muslims follow conjecture (hadith and
sunnah) instead of Quran alone (17:46) as our Creator has
commanded the “muslims” are divided into sects. These sects are
there because of differences and disagreements on Hadith rather
than disagreements over the Quran.
