Answer : At present, some areas observe Shiaam following the rising moon in Saudi Arabia. Saudi Arabia has been followed in some villages in the southern part of our country for a long time! Now the question is , is there any indication in the Sharia that the moon of Saudi Arabia will be the standard for the whole world ? So on what basis was Saudi Arabia accepted as the standard ? Saudi Arabia is not a far-fetched interpretation of the hadeeth , Rather, the westernmost territory is to follow the American state of Alaska. Above all, Islam is a simple and moderate religion. Its provisions are equally effective in all ages. Nowadays, due to the advent of the age of satellite, there is talk of celebrating Shiaam and Eid at the same time on the same day. But even a hundred years ago, when there was no satellite , was the non-Arab Muslim society forced to observe Shiaam on the day of prohibition of Shiaam, the day of Eid, simply because of lack of technical knowledge ? Does normal reasoning somehow justify it ? Is it possible to get news everywhere at the right time even in the age of modern satellite ? It is not at all possible considering the problems involved. For example , Korean [ GMT +9] Muslims have to wait at least 15 hours to find out if the [ GMT -6] moon has risen in America . In other words, the Muslims of Korea will get the news of the moon rising in the United States at 7 pm the next day at 11 pm local time. In this case, how will they perform the fast according to the principle of celebrating 'Shiaam and Eid on the same day' , and how will the Tarabeeh of that day be recited ? The time difference between New Zealand and Alaska in the far west of America is about 24 hours. Then New Zealanders will get the news of the American moon rising the next night. So what will be their way ? Wouldn't Taraki be deprived of having a fast every year ? Even in Bangladesh we have to wait till 6 am the next day to know the news of American moon rising. That is the same event! In other words, we Bengalis will not get the chhiyam or tarabeeha that day ! Again , let's say the news came 5 minutes before Sahari in Chittagong, Bangladesh that the moon has risen in America. In this situation, the people of Chittagong may have completed Sahari somehow , but what will the people of Rajshahi who are 13 minutes away from Chittagong do ? Even if they stay in the same country, they will not be able to keep Chyam , because by that time the time of Sahri is over! Then in the same country some people will keep Chhiam , some people will not keep it - think what a strange situation will be created ? And logically , we know that the morning line rises at the east end before the west end of the earth's surface. So as soon as the morning line rises in the eastern sky, will we leave the people of the western part of Sahari , while the night is still left in the west ? The answer is no . In the same way , when the sun sets in the eastern sky , will we start breaking the fast , even though we are still in the daytime ? The answer is no . So the moon and the sun are exactly the same in the case of Hukum. The moon is calculated monthly , and the sun is calculated daily. Therefore, in terms of logic and evidence, there will be separate provisions for each place in the case of Shiaam and Iftar. Which will be related to the external signs or symbols , which Allah Ta'ala has determined in the Qur'an and the Prophet (sm) in his Sunnah. And that is to start and end Ramadan by observing the moon and to observe Sehri and Iftar by observing the sun or Fajr. People will break the fast depending on the moon sighting in the area where they will be. (Muttafaq alaih , Mishkat H / 1989) Rasulullah (sm) said , ' You should fast when you see the moon and break your fast when you see the moon' (Bukhari , Muslim , Mishkat H / 1980) ; From this hadith it is understood that as soon as he sees the moon in his area , he will start Eid and end his fast and celebrate Eid. Allah the Almighty said- “(Muhammad SAW) they ask you about the new moon. Say: It is a means of setting the time for man and setting the time for Hajj. ”(Surat al-Baqara: 189) The Prophet (peace and blessings of Allaah be upon him) said:“ O Allaah ! Your ****. " (Jame Tirmidhi , Hadith: 3451) Whoever among you gets this month (Ramazan) , let him keep Shi'am '(Baqarah 185). The Prophet (peace and blessings of Allaah be upon him) said , “ You will start fasting when you see the moon (of Ramadan) and you will break your fast when you see the moon (of Eid). If the sky is cloudy (and the moon is not visible) then 30 days of the month will be completed. ” (Sahih Bukhari Ta. 1906 , 1908-1911) He made the sun shining and the moon shining and ordained for it various stages , so that you may know the reckoning of the year and the reckoning (of time). GOD has created them justly. He explains the verses in detail for the people of knowledge '(Yunus 5). Qurayb Tabei says that the daughter of Haris (Luba-ba) sent him to the emperor Mu'awiyah in the province of Sham. Then I came to Syria to meet his needs and while I was in Syria the new moon of Ramazan rose and I saw the moon on Thursday evening , then came to Medina ; Then Abdullah bin Abbas (R) asked me , "When did you see the moon (of Ramazan) ?" I said , on Friday night ; He said again , "Have you seen it yourself ?" I said yes and other people have seen it and Muawiyah and Shambhas have fasted. Ibn 'Abbas (R) said , "But we saw the moon on Friday evening , so we will continue to fast." Until the 30th or 30th before the 29th moon is seen. I said , do you not fast and observe Eid depending on the sighting of Muawiyah's moon and his fasting ? Ibn 'Abbas said , " No ; This is what the Prophet (peace be upon him) commanded us to rely on to see the moon of our countrymen ; We will not respect the sighting of the moon in other distant lands. ”(Sahih Muslim) We hope that in this discussion we will clearly understand that it is not possible to celebrate Sehri and Iftar at the same time in all the countries of the world . Celebrating Eid on the same day is not in accordance with Islamic law.
