Here's where you can read dozens of free classical Arabic texts
The Library of Arabic Literature produces a ton of famous Arabic texts, many of which only previously existed for Americans and Europeans in antiquated Victorian editions or in specialised libraries.
The paperback editions contain the English translation; the hardback both Arabic and English side-by-side.
You can download just the Arabic texts—up to date and comprehensively edited by some of the best Arabists in Western universities—as PDFs for free below.
