Early period (h. I-III) works are the most basic data sources in tafsīr studies. However, the related works were shaped within the conditions of the period. In this process, the literacy and schooling rate is low. It is not easy to obtain sufficient writing materials. For this reason, the information was initially transferred as a verbal, some of the original material that has been written has not survived. The information, which is usually narrated and sometimes written, can be learned through (...) the written copies of the next dates. However, there are serious time intervals between the author and the manuscript copies. This time period has led to some problems. There are such works that the author is controversial. There is such information that it is obvious that it was added later. Although some works belonging to the period were compiled from the sources of the following centuries, they were printed under the name of some people who lived in the early period, as if they gave the impression of author copy. Each of these matters has the quality to affect the nature of the information to be used as reference and the perception to be created on it. The relation of the subject with the interpretation of the Qur'ān and the fact that it is binding has a special importance, therefore, it requires knowing the formation stages of the reference source, especially in the commentary of tafsīr. In the article, the author-work relation in early tafsīr works has been tried to be processed on a sufficient number of examples with their respective dimensions.Summary: Early works in tafsīr studies are the most basic data sources. However, the related works were shaped within the conditions of the period. The data at the beginning were verbally transmitted, but some original material that has been written has not survived until nowadays. Therefore, the information about tafsīr are derived from the mainly Buhkārī (d. 256/870), Muslim (d. 261/875), Tirmidhī (d. 279/892), Nasā’ī (d. 303/915) which have tafsīr contents, and encyclopedic sources which have been contended narrations suhc as Țabarī (d. 310/923) and Ibn Abī Ḥātim (d. 327/938).Some later dated work/s belonged to people who lived in the early period alo contribute to this accumulation. However, in scientific studies it is necessary to pay attention to the harmony or difference between the author manuscripts and copies which have been survived. Because the limited possibilities of the period, the time interval between the author and the writing copy, the corrosion that occurred in the texts over time, the capacity or thought the scribe has caused the addition and reduction of the original copy of the text. Although it is rare, it is also possible to attribute the work to a well-known person of the period in order to gain the reputation of the views in the work.In this regard, the article first draws attention to the time difference between the author and the copies that have survived to the present day. Accordingly, it was emphasized that there may be works with controversial belonging to the author. Because, it may be that the names of those who expand, explain or shorten the work with additions are given as the author's name.It is shown with examples that additions to the work could be made in the time interval between the author and the manuscript that has survived to the present day. However, sometimes the difference between copies can be based on many reasons, from the ignorance of the obscene to its forgetfulness and even deliberate replacement. Even in the hadith narrations that attribute special importance to its narration, it is quite possible that the additions were made intentionally or unknowingly, even after the transition to the written period.However, this study was carried out only on tafsīr works. Because even the sampling on a limited number of tafsīr works pushes the limits of the article.In the study, the original texts of the selected works as samples such as Ibn ʿAbbās, al-Farrāʾ, Abū ʿUbayda, etc. were reviewed, and the master's and doctorate studies on the relevant works and the period, especially their editorial evaluations, were tried to be examined as much as possible. In the evaluations, the classical period sources such as Ibnu-Nadīm, Thaʻlabī and Ibn Khallikān, where tafsīr works were subject, as well as the Ottoman period like Edirnevī; Modern era works such as Brockelman and Sezgin were used. Books, articles and encyclopedia articles evaluating the manuscripts were also used.The study revealed that when the early tafsīr references were given, the author-copy relationship should be taken into consideration. Because, although some names are mentioned as mufassīr in the sources, it is controversial whether some of them convert the relevant information into written form. Because the period of the compilation is started in the period of tâbiûn in its earliest form. It is understood that even though the writing is partially activated, the tendency to convey information by narration continues from the examples given.The fact that no original work of the period reaches the present day, there is a serious time gap between the oldest manuscripts carrying the relevant information to the present day and its authors raises the issue of the reliability of the information. This is an issue to be considered in research and updating of information. Because it was seen that some information was difficult to determine the author. In addition, it has been understood that there may be additions afterwards besides the possibility of missing or misreported information due to various factors during the transfer. The fact that narration analysis has not been done properly in the context of the tafsīr science can lead to wrong conclusions in some works, if the possibility of reaching the information added later has not been taken into consideration.In addition, creating author copies from manuscripts is a challenging process with some difficulties in itself. No matter how fastidious it is shown, it should not be forgotten that the work is compiled from manuscripts, it should be known that errors may occur despite the maximum sensitivity.It is another point to consider that some information should be associated with the author and turned into a book based on the narrations in the sources of the next period. It should not be forgotten that some works were created by collecting the narrations of the next period. When the process in its formation is not taken into account, there is a possibility that the relevant information creates an early perception of false perception, as well as the belief that it expresses correct and precise information in all aspects due to its connection with the sacred. It is obvious that there is a difference between the original information from the author's pen and the quality and knowledge value of the information collected by claiming belonging to the author from later works. It is necessary to pay attention to this difference in information transfer.Therefore, during the investigation of the envoy, whose main task is to determine the will of Allah, he has to take into account the mentioned features of the early works. Reliable knowledge transfer and correct religion perception can only be achieved with this care. (shrink)
