The introduction states: "Muslim theologians make no distinction between the Quran and the Hadiths. Both are considered works of revelation or inspiration.... In the Quran Allah speaks through Mohammad; in the Sunnah he acts though Mohammad....The Quran cannot be understood without the aid of the Hadith, for every Quranic verse has a context which only the Hadith provide."
