An existence, so full of stirring events as that of the Prophet Mohammad, cannot be described by us in all its details. As there are limits to all books, we have had to rest content with a selection of the most important episodes, so that each might be developed as we deemed necessary. Thus we present to the reader a series of pictures and not a complete history.<br><br>Our scaffolding and sketches are borrowed from very ancient authors such as Ibn Hisham, Ibn Sad, etc., without forgetting a more modern writer, Ali Borhan id-Din Al-Halabi who, in his book known by the title of "Es Sirat al Halabia," gathered together different versions from all the best-known historians. An incontestable proof of their veracity, in our opinion, is that these narratives, some dating as far back as twelve centuries, fit in perfectly with the manners, customs, hopes and language of the Moslems of the desert; those who at the present day, by their mode of living, are more akin to the Arabs of the Hijaz among whom Mohammad accomplished his Mission.<br><br>These remarks will serve to warn the reader that in this work will be found none of those learned paradoxes destined to destroy traditions, such sophisms delighting modern Orientalists by reason of their love of novelty.<br><br>The study of innovations introduced in this way into the Prophets history has caused us to note that they were often prompted by feelings inimical to Islam which were not only out of place in scientific research, but were also unworthy of our epoch. As displayed by their authors, they generally denoted strange ignorance of Arab customs, notwithstanding that these commentaries were accompanied by considerable erudition, although too bookish. In order to refute such new-fangled assertions, it was enough to check each in turn. Being so contradictory, one killed the other. Their extreme improbabilities, from the standpoint of Oriental psychology, only served to enhance with still greater clarity the perfect likelihood of those traditions sanctioned in the world of Islam.<br><br>We have been guided by them.
