There are two widely accepted definitions of ilm al-tafsīr in the hāshiyahs on Anwār al-Tanzīl. The most accepted ones are as follows: Tafsīr is the science that investigates the states of the word of Allah in terms of signifying the will of Allah. This definition mainly belongs to al-Taftāzānī in his hāshiyah on al-Kashshāf. Despite the objections directed to it, the definition was accepted in the later phases and there were not any detailed discussions on it. From this point of view, it can be concluded that there is a common tafsīr definition in Anwār al-Tanzīl hāshiyahs due to the fact that the majority concurred with this definition. The prevalence of this definition is also out of the question for al-Kashshāf hāshiyahs. Its prevalence in the following literature may be attributed to its implementation in accordance with the definition requirements. Because in the definitions made based on the subject, the subject is regarded as genus, and how this subject is addressed is also considered as a difference (fasl). Accordingly, in the above definition, the subject of the tafsīr is explained as the states of Kalam, and the direction in which it is addressed is expressed in terms of the will of Allah. Thus, the subject of tafsīr and its research direction were explained and its difference from other sciences researching the Qur’ān was also stated. According to the second most widespread definition in the hāshiyahs, tafsīr is a science in which the meanings of the Kalam of Allah are known in terms of human capacity/capability. This definition is more or less a description (rasm) compared to the previous one. Hence, it is a looser definition. For this reason, the definition does not allow tafsīr to be separated from other sciences. Because, the meanings of words in the Qur’ān, language sciences and religious sciences are also explored. However, in the other definition, the difference of tafsīr was taken into consideration by including the directional record and the will/intent expression more quickly. On the other hand, the second definition has a limitation of being based on human capacity/capability that reveals some features of the tafsīr more clearly. This limitation expresses that the research in tafsīr is based on suppositional data in one way and continuity in another. Both definitions in the hāshiyahs show that there are clear and common definitions of ilm al-tafsīr between the hijri 9th and 12th centuries. It is stated that with a few exceptions, in almost all of the hāshiyahs, the ilm al-tafsīr is divided into two parts as tafsīr and ta’wīl. The tafsīr here is based on narrative, and ta’wīl is based on reason. Explanation of both of them in this way can be seen in al-Kashshāf. Accordingly, it is understood that both concepts become evident in al-Kashshāf and Anwār al-Tanzīl hāshiyahs. However, when we look at some tafsīr introductions, and literature of ulūm al-Qur’ān, it is observed that vastly different explanations have been made about them. This gives the impression that there is no clear and widespread acceptance of them. However, by explaining as mentioned, their meaning becomes clear in the next literature. Because this explanation about them is essentially a statement that al-Māturīdī conveyed from his predecessors. Accordingly, an explanation about both concepts that was conveyed from the early period has gained acceptance and became widespread especially in the sharhs-hāshiyahs for the following process. Since al-Baydāwī associates both concepts with muhkam and mutashābih, the commentators also explained this relationship. They contain the definitions of the muhkam and mutashābih, which al-Baydāwī made in accordance with Shāfi‘ī method. Accordingly, muhkam are the ones that is clear in terms of what is meant, and do not need further explanation. Examples of muhkam are verses about shari‘a 'orders, inheritance distribution, transactions, and marriage issues. The provisions on these issues should be based on narrative, not reason. Thus, the explanation of muhkam becomes tafsīr. The mutashābih is interpreted since the meaning is not clear. In this case, their interpretation is also ta’wīl. The religious sciences that tafsīr benefits from are explained as being hadith, fiqh, theology, mysticism, and usūl al-fiqh, and this case expresses a general opinion. Literary sciences required for tafsīr are also described as glossary, derivation, morphology, grammar, bayān, ma‘ānī, and badī‘. However, there are two opinions about the knowledge of disciplines such as prosody, rhyme, qard al-shi‘r, khat, and inshā. According to one opinion, since these sciences are not related to the Qur’ān, it is not necessary to know them in order to interpret them. According to the other one, for a competent interpretation activity, these sciences must be known, and their data are thought to contribute to tafsīr.
