Muhammad ibn Yahya has narrated from Muhammad ibn from Muhammad ibn ‘Isa from Yusuf ibn ‘Aqil from Muhammad ibn Qays who has said the following: “Abu Ja’far (a.s.), has said, ‘If two witnesses testify before the Imam to their seeing the new moon after thirty days, the Imam issues a commandment to discontinue fasting.

He (the Imam) performs Salat (prayer) on that day if they have seen it before Zawal (declining of the sun toward the west at noontime), but if they see it after Zawal, the Imam issues a commandment to discontinue fasting on that day and delays Salat (prayer) for the next day.”’ صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (16/409))
