The Muslims' cooperation in sighting the crescent and informing the responsible authorities of its sighting

Question: The brother N. S. G. from Tamir says in his question: What is the obligation of a person if he sees the crescent of Dhu al-Hijjah and does not inform the competent authority? And does the ruling differ if it is the crescent of Ramadan?

Answer: It is obligatory for the one who sees the crescent on the night of the thirtieth of Sha'ban, or the night of the thirtieth of Ramadan, or the night of the thirtieth of Shawwal, or the night of the thirtieth of Dhu al-Qa'dah to inform the court in his city, unless he knows that the crescent has been established by the sighting of another, acting in accordance with the saying of Allah, the Exalted: [Al-Ma'idah: 2], and His saying, the Exalted: [Al-Taghabun: 16], and the saying of the Prophet (peace and blessings be upon him): the hadith, and his saying (peace and blessings be upon him): the hadith.
It is known that the one in authority, through the Supreme Council of Judiciary, asks the Muslims that the one who sees the crescent must inform the courts. And the Prophet (peace and blessings be upon him) said: meaning the crescent and there is no way to act upon these hadiths except with the success of Allah, then with the cooperation among Muslims in sighting the crescent, and informing the responsible authorities of those who saw it. By this, compliance with the religious commands is achieved, and cooperation in righteousness and piety, and success is from Allah.
