Q: Assuming differences arise amongst the religious authorities with respect to
the affirmation of ‘Id al-Fitr, what is one’s duty? Ought each follower to refer
to his/her own marja‘?
A: Following one’s marji‘ has no role in relation to the new moon’s affirmation;
rather, assuming one acquires certainty, with respect to the new moon, by means
of a marji‘s announcement then one ought to break one’s fast on that day.
Assuming one has doubt (post-announcement) in relation to the matter, then
he/she must fast on that day.
