Fasting: Fine Crescent on ‘Īd Night — Was Shawwāl Declared Prematurely?

English:

Question #841:

If on the evening of ‘Īd of Fiṭr, the moon appears as a very fine crescent having the same characteristic of the new crescent, does it mean that the next day is the first of Shawwāl and that the ‘Īd was declared by mistake? Is one required to perform qaḍā’ for the last day of Ramadan?

Answer #841:

The thinness or thickness of the moon and also its size and position in the sky are not shar‘ī evidence in deciding the first or second of a month. But if it brings conviction to the mukallaf, he is obliged to act in accordance with his knowledge in this case.
