Faking manuscripts in Arabic script has a long history. The prospective targets of these fakes are various groups that have remained fairly constant over the centuries: bibliophiles and collectors are very prominent among those who acquire dubious items, but fakes were also prepared for scholars or pious individuals. Various techniques have been used, sometimes doctoring an original manuscript, sometimes producing a new one imitating an older model. Even facsimiles which were produced in good faith may have been turned into fakes in some cases.
