Abdul Alhazred

 was the author of the Necronomicon.

''Abdul Alhazred was the fictional invention of H. P. Lovecraft. Many hoax Necronomicons have been published since his time. Lovecraft encouraged writers in his circle to borrow ideas like the Necronomicon for their own works to create a sense of verisimilitude. Other fictional Cthulhu Mythos tomes created by his fellow writers have also appeared in Doctor Who. ''
