I read in a book that it was haram to fast on Eid if so then is it haram if some people in my town celebrate eid but others like my masjid celebrate the day after. Is it haram to fast while others are celebrating Eid in the same town?
If u trust your mosque, and they are not doing eid tomorrow, then fast with them. and if you dont trust them then dont fast tomorrow and participate the eid salah in another mosque.
