Time restrictions in the Holy Quran

The book contains three chapters preceded by an introduction and followed by a conclusion. As for the introduction, its title was "Introduction to the Terminologies of the Title, which are the Restriction, and the Time," and perhaps these words have roots before the era of the noble message. As for the three chapters, the work proceeded in two successive directions: one studying these restrictions in books of grammar and language, and the other accompanying it, which is studying these restrictions in the Holy Quran. The researcher relied on a methodology based on investigations, and most of the study was accompanied by precise statistics, except for a few parts due to the many points of disagreement, so I preferred to omit the statistics to avoid potential issues that the researcher might face.
