فَإِنْ غُمَّ الْهِلَالُ عَنِ النَّاسِ، وَشَهِدُوا عِنْدَ الْإِمَامِ بِرُؤْيَةِ الْهِلَالِ بَعْدَ الزَّوَالِ: صَلَّى الْعِيدَ مِنَ الْغَدِ.
Translation: If the moon was obscured and credible testimony of sighting reached the imam after noon, the Eid prayer is conducted the next day.
The first day’s valid Eid-prayer interval has elapsed when the testimony arrives. The deferral arises from delayed establishment of the Eid date, not voluntary postponement.
