I have dealt with in this research the topic of (the theory of astronomical calculation and astronomical vision); Explaining all the important and special aspects of it, according to my human capacity. I divided my research into an introductory chapter and three essential chapters: In the introductory chapter, I spoke about the reality of astronomy, astronomical calculations, new moons, timings, and the concept of worship. As for the first chapter: I dealt with the subject of the general theory of timings and legal obligations in the field of worship and its divisions; I talked about basic issues in the timing of legal obligations in the field of worship, and the sections of worship and how they relate to timing. In the second chapter, I talked about the extent of the influence of the crescent moons and times on the legal obligations in worship; So I explained the importance of the crescent moons and times in worship, and explained the position of the jurists and their evidence towards the difference of sightings and its relationship to the confirmation of the sighting of the crescent, and the difference in considering the sightings between the lunar months, and the position of the jurists in working with astronomical calculation and astrological vision, supported by my research on the legitimacy of the timing of worship in the honorable legitimate sources. And in the third chapter: I explained the most important provisions of the new moons and timings in the obligations in the field of worship, and I clarified them by defining the criterion for setting their timings in: purification, prayer, fasting, zakat, and pilgrimage. Finally, I wrote the conclusion, including some results. Such as the permissibility of working with the astronomical calculation and its adoption - supported by eye-vision, or alone -. And the permissibility of using astronomical observatories to monitor the crescent without conditions. No consideration according to the readings, which is correct. Likewise, the people follow Mecca in confirming the month of Dhul-Hijjah according to the majority of jurists, past and present. I concluded by proving the glossaries of the noble texts, topics, sources and references.
