Today's free book is
The Bible, the Koran, and the Talmud, or, Biblical Legends of the Mussulmans by G. Weil. As you can tell from the use of the word "Mussulmans" in the title, this is a quite old book (mid-19th-century), but it is still useful for getting basic information about these Islamic storytelling traditions.
