"This is an accurate study of the well–known problem of the accusation of distortion and falsification of the Scriptures brought by the Muslims, right throughout history, against Jews and Christians. This is a subject that has weighed heavily on the relations between the communities of believers. It is therefore useful that, from time to time, someone takes stock of this problem in a rigorous and scientific manner since the significance of the accusation has not always been understood in its strictly rigorous exactitude."Michel Lagarde in Islamochristiana 37 (2011), p. 342.“La monographie de G. Nickel constitue l’exposé le plus complet à ce jour sur le thème coranique de l’altération des Écritures par les Gens du Livre.”J. Dean in REVUE D’HISTOIRE ET DE PHILOSOPHIE RELIGIEUSES 2012, Tome 92 n° 4.
