I was browsing the library of the Wellcome Foundation recently when I came across this 19th century Malayan black magic charm (Ilmu Sihir) intended to curse its recipient with a fatal illness. The Arabic letters surrounding the human figure are incantations and spells written in the language of Djinns and Syaitan (demonic spirits). It is from the Hervey Collection of Malay manuscripts, 19th century. Wellcome Library no.: Wellcome MS Malayan 2E.
Malaysia, along with other southeast Asian nations, has long had a fascination with black magic and the supernatural. You can find more examples here.
Warning: If you are planning to use this on your enemies you should know that murder by black magic is still murder and the courts will judge you accordingly!
