I used to think it was a sign of our poor unity as a muslim ummah worldwide, that even city to city the celebrations of eid can be on different days depending on when the masjid committee sees the moon.
Now I’m beginning to see it from a different perspective. Each country at least, should have it’s own committee on this sort of thing, because if we were all to follow Saudi Arabia, it would centralize the religion around one country and it’s cultures too much. It would set a bad precedent, it would mean we have to follow SA in other situations as well. If anything, the right to sight your own moon and practice your eid when you want to, is essentially a manifestation of your right to following your religion without an intermediary of a pope-equivalent, which would be filled otherwise automatically by Saudia Arabia’s clergy.
So to all those who sighted their own moon. Here here.
