Authenticity is an essential issue for all religions, and a particularly acute one for those in which the written word plays a central role - and Islam is one of them, despite its insistence on the value of oral tradition. This raises questions both about the origin of the message and about scrupulous fidelity to it. Emerging religions face many challenges, as Reuven Firestone reminds us, drawing on Rodney Stark's theses:
[...] for a new religion to succeed, [...] it must retain cultural continuity with the religious systems of the societies in which it develops, while [...] maintaining a certain level of tension with its environment [1].
It must also demonstrate its authenticity
[...] by incorporating identifiable realia from earlier religions [...] through identification with an authentic religion, while at the same time attracting followers by establishing its uniqueness [2].
Muslims have a deep respect for the text of the Koran, due to its very status as the ipsissima verba of God, as al-A'zami affirms:
That the 'Uthmani Muṣḥaf contains the unadulterated Words of Allāh as sectioned into 114 surahs, is the firm belief of the Muslim umma ; anyone eschewing this view is an outcast [3].
