Revelation in the Qur'an

In Revelation in the Qur'an Simon P. Loynes presents a semantic study of the Arabic roots n-z-l and w-?-y in order to elucidate the modalities of revelation in the Qur'an. Through an exhaustive analysis of their occurrences in the Qur'an, and with reference to pre-Islamic poetry, Loynes argues that the two roots represent distinct occurrences, with the former concerned with spatial events and the latter with communicative. This has significant consequences for understanding the Qur'an's unique concept of revelation and how this is both in concord and at variance with earlier religious traditions.
