2)The seeing of the new moon becomes official by the testimony of one upright Muslim.
The Bedouin said : "Yes." Then the Prophet asked him "Do you profess that Muhammad is the messenger of Allah ?" The Bedouin answered : "Yes". The Prophet then ordered Bilal (his muazzin) to call on the Muslims to fast the next day".
5) Likewise, in case of the new moon of Sha'ban not being visible because of bad weather conditions, Ramadan shall be a full thirty days, on the strength of the prophet's instruction to "fast when you see the new moon and break the fast when You see the new moon and if it is hidden by cloud or fog, count thirty days".
This information is published in advance of every lunar year. Therefore, a man who has acquired this information can, even when he can not actually see the new moon, fix the beginning and end of his fast accordingly. The Prophet says in this connection: "Fast when you see it, and break the fast when you see it ; but if you cannot see it, calculate it." In his commentary on the Quran, al-Qurtubi said : "Matraf Ibn Abdullan, a prominent figure of the generation following the Prophet, and Ibn Qutayba, a famous linguist, stated that astronomical calculations should be resorted to in cases of cloudy skies, and that these calculations be regarded as official." This verdict was accepted at a time when the knowledge of astronomy was not so extensive and accurate as it is today. Such a verdict should be even more acceptable at the present time.
It is to be noted here that the Prophet, addressing the ordinary man, ordered that the month be counted as thirty in case the new moon could not be seen ; whereas, addressing people to whom astronomical knowledge was available, said that the month should be calculated.
This is an example of the wisdom of the prophet in addressing each group of people according to their educational standards.
"I saw the new moon in Damascus on Friday. At the end of the month I arrived in Medina. Ibn `Abbas asked me about the new moon and I said that I and everyone else had seen it on Friday, and that everyone including Mu'awiya observed the fast on that day. Ibn `Abbas said that the people in Medina had seen the new moon on Saturday and that they were still fasting in order to complete thirty days. I asked if the witnessing of the new moon and the fasting of Mu'awiya were not enough testimony for him. Ibn `Abbas replied "No, for this is how the Prophet instructed us".
Medina, where Ibn `Abbas lived, is to the east of Damascus. That is why Ibn `Abbas had to abide by the Prophet's instructions until the new moon could be seen on Saturday in Medina.
8) If the new moon is seen in any country, the people of every other country falling in the same day longitude should observe the fast on the same day.
9)
There is a school of Muslim thought which considers that the people of
any country where the new moon is seen can deputize for all Muslims everywhere
in the world. Thus fasting begins with the seeing of the new moon in that
country, likewise in all other countries even though the new moon might
not have been seen there.
