Asma Hilali's reconstruction of the Sanaa Palimpsest affords a privileged glimpse into the most fundamental aspect of qur'anic studies: the recovery of very early fragmented (and often indecipherable) texts. ... Though hers is a highly technical study, Hilali writes with such clarity, ... that even non-specialist readers will find it useful, and, indeed, fascinating. ... The annotated edition of both texts is quite simply masterly. It is on the foundation of such determined and painstaking labour as Asma Hilali has performed that subsequent syntheses, ... must eventually depend.
