 Differences in hadith collections have contributed to differences in worship practices and shari'a law and have hardened the dividing line between the two traditions.In the Sunni tradition, the number of such texts is somewhere between seven and thirteen thousand, but the number of "hadiths" is far greater because several "isnad" sharing the same text are each counted as individual hadith.If, say, ten companions record a text reporting a single incident in the life of Muhammad, hadith scholars can count this as ten hadiths.
