Renowned
scholars of Hambali Madhab explain:
"Kuraib's Hadith informs us that they did not
celebrate Eidul Fitre depending on Kuraib's words. We also say the same. The
question is whether compensation for the lost fast of the first day of Ramadan
became compulsory. That is not mentioned in the Hadith." (Mugni 3-5)
In short there is no mention in any Hadith that the information of the Hilal seen elsewhere should be rejected or that the Prophet (saw) has specified the limits to accept the witnesses. The reason is that there would be difference in the appearance of the Hilal and it should not be determined according to the distance. Moreover, it changes every month. Moonrise and moonset for every day for any given place can be determined exactly by calculations. We can see in the practice of the Prophet (saw), the directions to the effect that the differences in moonrise shall not be considered in the case of determining the onset of the month.
