Introduction to the Hadith [PDF ebook] 

The Hadith are believed to be the words of the Prophet, memorised by his followers and written down in the first or second centuries AH. This is a clear introduction to the arguments surrounding both the Hadith and the documents themselves. Comparing the views put forward in the Hadith with those of the Qur’an, it takes the student through all aspects of the Hadith in clear and accessible terms.
