The Islamic jurist guardianship in issuing the rulings to prove the crescent sighting and the jurist authority in the arena of politics and management of society and the analysis of its astronomical consequences found a special place after the glorious Islamic Revolution of Iran. Since no comprehensive research has been carried out on the extent of its influence among the Mukalafan (accountable people), the question on the Islamic jurist guardianship in issuing the rulings to prove the crescent sighting and its extent of influence among the accountable people is an issue that deserves an appropriate answer. This study, which has been derived from the analysis based on the generalities and absolutes of the arguments of Wilayat-e-Faqih, indicates the reliance on the most of jurists' viewpoints in the related doubt. Because it must be proved that one of the governmental responsibilities of the Imams was to issue the ruling for proving the crescent sighting in order to rely on them correctly. Considering the completeness of Muhammad ibn Qays' correct arguments, the jurist guardianship in issuing the rulings to prove the crescent sighting can be concluded, and all the objections to it are rejected. Although other arguments in its authenticity have been put forward by some, due to the lack of authenticity of the documents or the reasons, they only play a role in confirming the claimed viewpoint. . According to the above-mentioned correct arguments and the concept of priority, the ruling is valid only if it is based on evidence and generality, and not on the knowledge and vision of the jurist himself. According to the analysis of the accepted phrases of Umar ibn Hanzalah, the rulings issued by the jurist, including the aforementioned ruling - in case of certainty of the jurist's error in the ruling or his error in the subject or knowledge of his error in the documents of the ruling or subject - is valid for all accountable people in the area of the jurist's governance and proving the crescent sighting becomes absolute and the religious effects of this event can be resulted.
