Ruling on fasting and breaking the fast of one whose testimony was rejected or who was not able to inform the authorities

 

If a person sees the new moon of Ramadaan but could not tell the superiors or was not believed about seeing it, should he fast alone, and what about Eid? Should he break the fasting alone?.

Praise be to Allaah.

Some of the scholars are of the view that he should fast by
himself, but the correct view is that it is not permissible for him to fast
by himself or to break the fast by himself, rather he should fast with the
people and break the fast with them, because the Prophet (peace and
blessings of Allaah be upon him) said: “The fast is the day when you
(plural) fast and the breaking of the fast is the day when you break the
fast.” But if he is in the wilderness and has no one with him, then he may
start and end the fast on the basis of his own moon sighting. End quote.
