The hunt for the "sources" of the Qur’ân became almost a fashion and in the year following the publication of Claire Tisdall’s Sources of Islam, i.e., in 1902, there appeared the New Researches into the Composition of the Koran by H. Herschfeld, which was published by the University of London Press. It did not really open up any new ground and trod mainly on the beaten track. Another work on the supposed source of the Qur’ân was prepared in French by Cl. Huart entitled Une nouvelle source du Qoran (A New Source of the Qur’ân) which was published in 1904. Almost similar in nature, but following more the foot-steps of N?ldeke, was E. Sell’s The Historical Development of the Qoran published in 1905. Another work touching the supposed "sources" of the Qur’ân but more academic in nature was Robert Roberts’ The Social Laws of the Qorân Considered , and Compared with those of the Hebrew and other Ancient Sources. It was originally written in German as a Ph. D. thesis early in the twentieth century and submitted to the Leipzig University; but was subsequently translated into English and published for the first time in 1925. It deals with such matters as marital relations, slavery, inheritance, charities, criminal offences, trade and commerce and food, the author’s plan being, as stated in the preface, to trace the Prophet’s "enactments where possible to their sources". In the notice on the jacket of the book it is further stated: "Muhammad ... appeared as a social reformer as well, and ... allowance must necessarily be made for the debt which Islamic laws owe to those found in the Old Testament and Talmudic literature."

The ideas and assumptions transmitted through the above mentioned publications percolated into general works published at the time on Islam and Prophet Muhammad (صلى الله عليه وسلم). A characteristic instance is the Oxford Professor David Samuel Margoliouth’s Mohammed and the Rise of Islam, the third edition of which appeared in 1905. It reproduces principally the views of Sprenger, Muir and N?ldeke
