The Shaykh’s guidance to people who begin Ramadan by fasting one or two days before others, and who break their fast before or after them?

Question:
The listening brothers often ask Shaykh Salih about the differences among people regarding fasting and travel. You find some people beginning the month of fasting one or two days before others, and breaking their fast after some people or before them, and so on. So what is the comment of the Honorable Shaykh Salih? And what is your guidance to the people, especially if they are in the same country or the same state? May Allah reward you with good.

Answer:
The Prophet (peace and blessings be upon him) settled this matter to clarify the issue. He said (peace and blessings be upon him): "Fast upon seeing it," meaning the crescent moon. "And break your fast upon seeing it." That is, if the sky is cloudy. It is not upon you [to worry]. So glorify Him for it. The crescent moon. Decision. This is from the aspect of the statement. And from the aspect of action, when the one who informed him that he saw the crescent moon came to him, the Prophet (peace and blessings be upon him) ordered him to fast based on the sighting. So the command is contingent upon seeing the crescent moon in fasting and in breaking the fast. If the people of the country see it, and it is not a condition that all the people see it, if one trustworthy Muslim sees it, then the Muslims fast based on his sighting, as the Prophet (peace and blessings be upon him) did when Ibn 'Umar informed him that he saw the crescent moon, so the Prophet (peace and blessings be upon him) fasted and ordered the people to fast. Likewise, when the Bedouin informed him that he saw the crescent moon, the Prophet (peace and blessings be upon him) fasted and ordered the people to fast. If one or more Muslims see the crescent moon, then it is obligatory for the Muslims in the state or the country to fast, if that is established with the judge, the legal judge, or with the trusted mufti for the Muslims. It is not permissible for anyone to lag behind the Muslims in fasting or in breaking the fast, because the Muslims are one community who all fast together and all break their fast together. But if the countries are far apart and there is a difference in the moonrise times, because the moonrise times differ, according to the correct view, from one country to another, then every group has their own sighting. Every group from the regions where the moonrise times differ has their own sighting, so they fast based on their sighting and break their fast based on their sighting. So the matter is broad, and praise be to Allah, and there is no room for disagreement in this; because the matter is settled by the Lawgiver. So breaking the fast is based on seeing the crescent moon, and fasting is based on seeing the crescent moon. And if one of the Muslims sees it, then it is obligatory for all the residents in the province or the region or the country where the moonrise times do not differ, that they all fast. And if they do not see the crescent moon on the night of the thirtieth of Sha'ban, then they break their fast and complete the count of Sha'ban as thirty, as the Prophet (peace and blessings be upon him) said: May Allah reward you with good, and may He do you good.
