The Sunnat is now known to Musalmans through the collections of Traditions gathered together by the men whose names they now bear. The whole are called Sihah-Sittah, or "six correct books." Not one of these collectors flourished until the third century of the Hijra, and so, as may be easily supposed, their work has not passed unchallenged. There is by no means an absolute consensus of opinion among the Sunnis as to the exact value of each Tradition, yet all admit that a 'genuine Tradition' must be obeyed. Whether the Prophet spoke what in the Traditions is recorded as spoken by him under the influence of the highest kind of inspiration is, as will be shown in the next chapter, a disputed point; but it matters little. Whatever may have been the degree, it was according to Muslim belief a real inspiration, and thus his every act and word became a law as binding upon his followers as the example of Christ is upon Christians. The Shia'hs do not acknowledge the Sihah-Sittah, the six correct books of the Sunnis, but it by no means follows that they reject Tradition. They have five books of Traditions, the earliest of which was compiled by Abu Ja'far Muhammad A.H. 329, or a century later than the Sahih-i-Bukhari, the most trustworthy of the Sunni set. Thus all Musalman sects accept the first and second ground of the faith--the Quran and the Sunnat--as the inspired will of God; the Shia'hs substituting in the place of the Traditions on which the Sunnat is based, a collection of their own. What it is important to maintain is this, that the Quran alone is to no Musalman an all-sufficient guide.
