Last month’s most expensive sale, a rare Islamic book about the work and words of the prophet Muhammad, was our sixth most expensive sale in the history of AbeBooks and our biggest sale for five years. The $45,000 book is around 800 years old and details Hadith methodology. Hadith are collections of narrations dedicated to explaining the prophet’s actions and words. They are important tools in understanding the Qu'ran and Islamic law, and have existed for more than 1,200 years. They are a cornerstone of Islamic life.

Muhammad died in 632 A.D and his traditions were passed on orally for several centuries before the Hadith were formally recorded. By the 9th century, there were many different versions of the Hadith and today the Shia and Sunni denominations have different ones.

Most Darling of the Poetry section at Abe's Rare? Keats tied with Elliot. Oddly enough, Jim Morrison of the Doors comes in at #4. Go figure.
