Analytical study of the historical course of "necessary Waqf" in the knowledge of Stopping and the beginning of the Holy Quran

One of the most important signs of stopping and the first in the Holy Qur'an, the necessary endowment sign is "م". The current research tries to analyze the historical course of the necessary Waqf from the time of Sajavand, who was the creator of this type of endowment, to the time of contemporaries by adopting the descriptive-analytical method. After studying the necessary Waqfs, it was found that the verses in which the necessary Waqf sign is used, are mostly in the field of religious verses.In case of non-observance of the required endowment, it is possible to get an understanding contrary to the divine intention of the verses of the Holy Quran. This misunderstanding can go to such an extent that the divine intention of the verses of the Holy Qur'an appears to be the exact opposite. With the historical investigation, it is clear that from the time of Sajavandi to the contemporary time, the number of 16 items has been considered necessary in all periods; 3 items were first necessary, then unnecessary and again changed to necessary; 29 cases were necessary at the beginning, but became unnecessary until modern times; 3 items were initially unnecessary and became necessary until modern times; There were differences in 3 cases and there was no steady course.
