ومن رأى هلال رمضان وحده صام
Translation: Whoever sees the Ramadan crescent alone must fast.
The passage now distinguishes personal sighting from the community’s formal establishment of Ramadan. Someone who actually sees the Ramadan crescent must fast according to Quduri, even before considering whether the sighting is accepted for the public.
This does not give that person authority to issue a binding announcement for everyone; personal obligation and communal determination are distinct.
