Assalamu ʿalaykum wa rahamatullahi wa barakatuhu:
A host of recent publications have challenged the traditional view of the development of Islam. For example, Christoph Luxenberg has attempted to show that the Qur'an was drafted in a mixed Aramaic-Arabic tongue and based upon Christian Aramaic texts, contrary to the traditional view of its composition in Arabic or derived from Arabian religious traditions. On the other hand, Yehuda Nevo argued that the religious beliefs of the early Arabs constituted paganism along with 'a very simple form of monotheism with Judaeo-Christian overtones'. There is no doubt that the study of early Islamic history is contentious among Western scholars, where agreement about various issues is quite rare. In this kind of a situation, one might expect that the existing documents such as papyri, coins and inscriptions will be taken into account while formulating a hypothesis. Unfortunately, such has not been the case and the result of which is often the proposal of extravagant hypotheses on the origins of Islam. What makes this situation particularly bizarre is that the Western scholars have access to what can be called a treasure-trove of documentary evidence when compared with other major world religions. Judaeo-Christian scholars studying the earliest Christian artefacts are presently unable to call forward even a single item of documentary evidence from the first one hundred years of Christianity and beyond.
Our aim here is quite modest. It is to simply present the corpus of dated Muslim writings along with their contents from 1-72 AH / 622-691 CE. These writings include inscriptions, coins and papyri. By just going through their content, the reader would be able to establish certain landmarks and conclusions. Why the date 72 AH? This is because when we come to the Marwanid period, the dated Islamic texts become much more numerous and with varied content. After this period the citations from the Qur'an also begin to appear.
The list below is based on Robert Hoyland's collection with some additions from our side. Recently, Youssef Ragheb updated the list of dated documentary evidence by incorporating the latest findings. They are also included in the list.

2. Why Do The Dated Texts Appear From Early 20s AH?
The official Islamic calendar (or the hijri calendar) is lunar with year one coinciding with the year 622 CE, the date of Prophet Muḥammad's emigration (i.e., hijra) from Mecca to Medina. This era does not begin on the date of Muḥammad's arrival at Medina, but on the first day of the lunar year in which that event took place, which is reckoned to coincide with the 16th July 622 CE. Years counted according to the era of the hijra were introduced by the caliph ʿUmar bin al-Khaṭṭāb in 17 AH / 638 CE. He signalled the importance of Islam and declared that the hijra of Prophet Muḥammad would be used to set the official Muslim calendar. Since counting of years according to the era of hijra began in 17 AH / 638 CE, and that the official edict takes some time to percolate through the empire, it is not surprising that dated Muslim texts appear slightly later, that is, from 22 AH / 643 CE onwards. Furthermore, it is interesting to note the early adoption of the hijri calendar.
The hijra date is independently established from Islamic sources in dated inscriptions and papyri. Excluding Arabic-only papyri, there are dozens of Greek (e.g., Muʿāwiya's inscription at Hammat Gader, 42 AH / 662-63 CE), Greek-Coptic and Greek-Arabic (e.g., PERF 558 from 22 AH / 642 CE) papyri and inscriptions showing a hijra year in addition to a Greek dating. Likewise, similar examples can be found in Christian Syriac manuscripts showing the hijra dates.

 The most commonly quoted controversial Western scholars who attempted to reconstruct the early Islamic history are Patricia Crone and Michael Cook (Hagarism: The Making of the Islamic World, 1977, Cambridge University Press: Cambridge) and John Wansbrough (Qur’anic Studies: Sources & Methods Of Scriptural Interpretation, 1977, Oxford University Press; idem., The Sectarian Milieu: Content & Composition Of Islamic Salvation History, 1978, Oxford University Press).
 Even those sober publications which do make extensive use of the early dated corpus of evidence can inadvertently ignore some vital pieces of evidence. For example, whilst commending Beatrice Gruendler’s thorough use of the early dated Arabic texts in her volume The Development Of The Arabic Scripts: From The Nabatean Era To The First Islamic Century According To Dated Texts [1993, Harvard Semitic Series No. 43, Scholars Press: Atlanta (GA)], Healey and Rex-Smith note that vital pieces of palaeographic evidence are still absent. Specifically, with regard to coins, glass weights and stamps they lament, “for how much longer will these essential pieces of palaeographic evidence be forgotten?” See J. F. Healey and G. Rex-Smith, "Beatrice Gruendler, The Development Of The Arabic Scripts: From The Nabatean Era To The First Islamic Century According To Dated Texts", Journal Of Semitic Studies, 1995, Volume XL, No. 1, p. 177.
 L. W. Hurtado, The Earliest Christian Artifacts: Manuscripts And Christian Origins, 2006, Wm. B. Eerdmans Publishing Co.: Grand Rapids (MI), pp. 2-4. The earliest extant Christian inscriptions are from the third century CE. The earliest extant example of a Christian Church is from the third century CE. Hurtado says [p. 3]:
… Among these pre-Constantinian manuscripts, a small but growing number are dated as early as the second century, and these second-century manuscripts now constitute the earliest extant artifacts of Christianity.
