Prophets

Muslims believe that God sent Muhammad as the final prophet (" Seal of the prophets ") to convey the completed message of Islam. In Islam, the "normative" example of Muhammad's life is called the sunnah (literally "trodden path"). Muslims are encouraged to emulate Muhammad's moral behaviors in their daily lives, and the sunnah is seen as crucial to guiding interpretation of the Quran. This example is preserved in traditions known as hadith, which are accounts of his words, actions, and personal characteristics. Hadith Qudsi is a sub-category of hadith, regarded as God's verbatim words quoted by Muhammad that are not part of the Quran. A hadith involves two elements: a chain of narrators, called sanad, and the actual wording, called matn. There are various methodologies to classify the authenticity of hadiths, with the commonly used grading grading scale being "authentic" or "correct" (صحيح, ṣaḥīḥ); "good" (حسن, ḥasan); or "weak" (ضعيف, ḍaʻīf), among others. The Kutub al-Sittah are a collection of six books, regarded as the most authentic reports in Sunni Islam. Among them is Sahih al-Bukhari, often considered by Sunnis to be one of the most authentic sources after the Quran. Another well-known source of hadiths is known as The Four Books, which Shias consider as the most authentic hadith reference.
