What should a person do if he saw the new moon of Ramadaan or Dhuâl-Hijjah, and he did not tell the relevant authorities about that?
Praise be to Allaah.
What the one who sees the new moon on the night of the thirtieth of Shaâbaan or the thirtieth of Ramadaan or the thirtieth of Shawwaal or the thirtieth of Dhuâl-Qaâdah should do is to inform the court in his city, unless he knows that the sighting of the new moon has been confirmed by someone else, in accordance with the words of Allaah (interpretation of the meaning):
âHelp you one another in Al‑Birr and At‑Taqwa (virtue, righteousness and piety)â
âSo keep your duty to Allaah and fear Him as much as you can; listen and obeyâ
And the Prophet (peace and blessings of Allaah be upon him) said: âThe Muslim must hear and obey.â Narrated by Muslim (1839).
And he said: âI urge you to fear Allaah and to hear and obey, even if a slave is appointed over you.â
It is well known that the ruler via the highest judiciary council of Muslims requires the one who sights the new moon to inform the authorities. The Prophet (peace and blessings of Allaah be upon him) said: âFast when you see it (i.e. the new moon) and stop fasting when you see it, â¦ but if it is too cloudy then complete the number.â There is no way of following these ahaadeeth except by the help of Allaah, then by cooperation among the Muslims in sighting the new moon, and informing the authorities when it is sighted. The one who sights it has to inform the official authorities of that. Thus obedience to the sharâi commands and cooperation in righteousness and piety will be achieved. And Allaah is the Source of strength. End quote.
