Such questions that may it be essential, necessary, recommended, or free to believe in some matters will be addressed in the article. It is concluded that such an approach is possible for Māturīdis and Ash'arīs. In the study, it was thought that the following two problems should be solved first. The first problem is how can a definitive confirmation be made with speculative information (zannī). Second, if it is a contradiction that the ulema of the relevant school construct the subject of belief with an āḥād report (khabar) even though they explain the true report as mutawātir in the works of Kalām? In the article, three different solutions are proposed for the first problem, and the second problem is tried to be solved with the proposition that tawātur is compulsory for the universal or essential subjects of theology. Then, by giving two examples for each decree (hukm), it was tried to determine what this idea means in practice. It has been determined that the main controversial issues between the Ahl al-sunnah and the Mu'tazila arise in the category of wājib to be believed. It has been determined that the scholars of the aforementioned sects fall into dispute among themselves in matters presented as sunnah to be believed. As a result, in terms of the principles set forth by the Ahl al-Sunnah, it has been deemed possible to implement ʾafʿālu al-mukallafīn (deeds of those obligated) to theological issues. In our literature review, we did not come across a study solely focused on this subject before. In the introduction, information is given about the concepts of qatʿiyyatu al-thubūt – zanniyyatu althubūt (definitive-speculative confirmation), qatʿiyyatu al-dalālah- zanniyyatu al-dalālah (definitive- speculative implication), which are closely related to the subject. Then, theoretical information about the possibility of using such a classification in ʿaqīdah (Islamic creed) matters is presented. It can be mentioned that the concepts of faith and confirmation are important in this regard. It is expressed most of the Kalām scholars that belief is a confirmation without a doubt. In this context, the idea of forming a belief with speculative evidence emerges as a problem. In order to get out of the contradiction, three different explanations have been introduced. First, there is no obligatory relationship between confirmation and evidence. Therefore, a certain belief can be constructed with speculative information. Second, elements of belief based on speculative evidence are metaphorically called faith. In this context, only matters that are fard to be believed should be evaluated under the concept of faith in the real sense. Third, confirmation may contain hesitation. In this case, since the matters that are essential to believe are based on definite premises, a confirmation will undoubtedly be expected. On the other hand, it may seem possible that there is hesitation in confirmation in proportion to the weakness of the evidence. It is an undisputed judgment among Kalām scholars that knowledge on ʿaqīdah issues can be obtained through three methods: reason, senses, and true report. It has been stated that the true report is the mutawātir report or the word of the prophet supported by a miracle. Since only mutawātir news expresses information in Kalām, it is necessary not to try to prove an ʿaqīdah issue with āḥād news in theory. However, the Kalām books are full of contradictions to this decree. At this point, as a solution, it has been proposed to divide the subjects of Kalām into two as universal - partial or essential - ancillary. While only the mutawātir report plays a role in universal issues, it was expressed that āḥād reports on partial issues can also be accepted with presumptions. Therefore, besides the things that are essential to be believed, the elements that are necessary, recommended, or free to be believed become acceptable. The matters that are essential to be believed are related to the essential issues of religion, such as the existence of Allah, His oneness (waḥdāniyyah), and the possibility of sending Prophets (nubuwwat). These also contain the principles that constitute the essence of religion. The matters that are necessary to be believed include the main issues that Ahl al-Sunnah disagreed with the Mu'tazila. Ru'yatullah (seeing Allah in akhirah) and life in the grave (barzakh) are among these issues. In the article, brief explanations about these issues are given. The matters that are recommended to be believed are narrations based on āḥād, sahih reports. Intercession by martyrs and various emotional miracles attributed to the Prophet Muhammad (pbuh) have been evaluated in this context. The matters that are free to be believed are those for which there is no clear religious evidence. It includes matters such as the fact that man is more virtuous than the angels and the name of the angel of death (Malak al-Mawt) is Azrael. In conclusion, in terms of the principles of the Ahl al-Sunnah, it seems possible to use such a classification in the Kalām issues. [ABSTRACT FROM AUTHOR]
