 "Many thousands of times" more numerous than Quranic verses, ahadith have been described as resembling layers surrounding the “core” of the Islamic belief (the Quran).Well-known, widely accepted hadith make up the narrow inner layer, with a hadith becoming less reliable and accepted with each layer stretching outward.The reports of Muhammad's (and sometimes companions) behavior collected by hadith compilers include details of ritual religious practice such as the five "salat" (obligatory Islamic prayers) that are not found in the Quran, but also everyday behavior such as table manners, dress, and posture.
